MIC22200YML Evaluation BoardIntegrated 2A Synchronous BuckRegulatorRamp Control is a trademark of Micrel, Inc.Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 •General DescriptionThis board enables the evaluation of the MIC22200; a highpower density, frequency-adjustable synchronous buckregulator. The MIC22200 features integrated 2AMOSFETs, integrated frequency compensation, flexible sequencing and tracking abilities. The board is optimized for ease of testing, with all major components are on a single side. The voltage mode feedback loop is designed to allow high bandwidth with just 2 external compensation components. The high side MOSFET is a P-Channel one,allowing duty cycle control up to 100%.The Micrel MIC22200 is a high efficiency 2A Integratedsynchronous buck (step-down) regulator. The MIC22200 isoptimized for highest power density and achieves over85% efficiency whilst switching at 4MHz with only 1µHinductor and down to 22µF output capacitor. The ultra highspeed control loop keeps the output voltage withinregulation even under extreme transient load swingscommonly found in FPGAs and low voltage ASICs. Theoutput voltage can be adjusted down to 0.7V to address alllow voltage power needs. The MIC22200 offers a full-range of sequencing and tracking options. The enable/delay pin combined with the power good/POR pin allows multiple outputs to be sequenced in any way on turn-on and turn-off. The RC (Ramp Control™) pin allows the device to be connected to another MIC22200 device to keep the output voltages within a certain delta V on start up. RequirementsThis board needs a single bench power source adjustable over the input voltage of interest that can provide at least 2A of current. The loads can either be active (electronic load) or passive (resistor) with the ability to dissipate the maximum load power while keeping accessible surfaces ideally < 70°C. It is ideal to have an oscilloscope to view the circuit waveforms, but not essential. For the simplest tests, two Voltage meters are required to measure input and output voltages. For efficiency measurements, two voltage and two current meters are required to prevent errors due to measurement inaccuracies.PrecautionsThere is no reverse input protection on this board. Whenconnecting the input sources, ensure that the correctpolarity is observed.Under extreme load conditions such as short circuit testing, input transients can be quite large if long test leads are used. In such cases, place a 22µF or 47µF, 6.3V Tantalum capacitor at the V IN terminals to prevent over voltage damage to the IC. Getting Started 1. Connect V IN supply to the input terminals +V IN and GND . With the output of this supply disabled, set its voltage to the desired input test voltage. This supply voltage should be monitored at the test boards input terminals to allow voltage drops in the test cables (and ammeter if used) to be accounted for. An ammeter can be added inline with the +V IN input terminal to accurately measure input current as some power sources current andvoltage displays can be misleading. 2. Connect the loads to the output terminalsbetween +V O and GND . Again, this output voltage should be monitored by connecting the voltmeter at the +V O and GND terminals. An ammeter can be added inline with the +V O terminal of the evaluation board to accurately measure the output current. Initially, set the output load to 0A to check that the output is regulating properly prior to loaded tests. 3. Enable the input supply . By default, the outputvoltage is enabled when an input supply of > 2.5V is applied. When this threshold is crossed, the enable pin capacitor (1nF) begins to charge at 1V/µs until it reaches 1.25V, where switching begins. To test the Enable functions of the MIC22200, a test point is provided.Ordering InformationPart Number DescriptionMIC22200YML EVEvaluation board with the Integrated 2A MIC22200 deviceOther FeaturesEnable DelayC7 creates a delay set by an internal 1µA source charging to a 1.25V threshold. Using a switch-to-ground (Q1) using ‘Shdn’ to enable the part will exhibit approximately 1.3µs enable delay from ‘Shdn’ going low to the start of switching. Using a pulse generator with a low impedance output connected to the EN terminal will remove this delay as it defeats the internal 1µA source.RC (Ramp Control™) CapacitorThe MIC22200 has a nominal 1µA current source/sink to the RC pin. The startup output voltage waveform tracks the voltage on RC. 100% output voltage is represented by 0.7V on RC. The default capacitor on RC (C3) of 1nF therefore sets the ramp up time to approximately 700µs. Feedback resistorsThe output is set nominally at 1.8V. This can be changed by adjusting the upper or lower resistor in the FB potential dividers. It is recommended that R1 or R2 value should be kept <10k to reduce noise susceptibility and offset currents from creating voltage errors. Therefore, choosing R1<10k: R2 = R1 V REF/(V O – V REF)Where V REF = 0.7VDelayAdding an external capacitor to this pin allows the Power Good delay to be adjusted to perform as a Power-On Reset (POR). As with the RC pin, this pin has an internal 1µA current source and sink. When V FB reaches 90% of its nominal voltage (~ 630mV) the internal 1µA current source charges the capacitor on this pin (C4) to the rising threshold of 1.25V, at this point, PG is asserted high. When the enable pin is set low, POR is asserted low immediately. However, the internal ‘Delay’ current sink discharges the capacitor (C4) to 1.25V lower than its starting point, at which point, it enables the RC pin 1µA current sink to begin discharging C3. Power On Reset (POR)This is an open drain connection with an on board pull-up resistor (R3) to SV IN. This is only asserted high when the FB pin reaches >90% of its nominal set voltage. This can be used as part of the Tracking and sequencing function described in the data sheet.Typical Characteristics606570758085909510000.51 1.52OUTPUT CURRENT (A)V IN = 3.3VV IN = 5.0V 606570758085909510000.51 1.52OUTPUT CURRENT (A)V IN = 3.3VV IN = 5.0VFunctional CharacteristicsEvaluation Board SchematicBill of MaterialsItem Part Number ManufacturerDescription Qty.

Withdrawal system for solvents with manual pressure build-up for 10 l and 25 l stainless steel drumsHandling and safety notices Withdrawal system for solvents with manual pressure build-up for 10 l and 25 l stainless steel drumsHandling and safety noticesComponents• Withdrawal system with 2 exchangeable dip tubes for 10 l and 25 l stainless steel drums• Clamp for outlet tube• Ball valve tap• Pump ball• Three-way stopcockAdditional parts• 1.07070.0001 Antistatic device• 1.08803.0001 Key for opening drums and barrels• 9.67100.1026 Dip tube for 25 l – composite drums (steel/PE)Spare parts• 9.67100.1079 Hand pump ball with rapid-action connector• 9.67100.1048 Seal (O-ring 14x2.5 mm)• 9.67400.1047 Seal (O-ring 56x3.6 mm)Safety noticesGeneral warnings and safety instructions must be observed.The sampling system, particularly the sealings, should be checked for proper operation before each use.If flammable liquids (e. g. solvents) are to be used, the container must be properly earthed according to valid safety regulations to avoid explosion and fire risks. Appropriate measures must be taken to dis-charge static electricity. Both the withdrawal system and container must be grounded in accordance with the ap-plicable safety regulations. For this purpose the antistatic device (Cat. No. 1.07070.0001) can be used. Grounding clamps must have metallic contact with both the container and the withdrawal system, and a safe ground connection.It is important to ensure that both the container and the withdrawal system (e.g. at the outlet tube) are grounded separately. This measure prevents electrostatic separation of charges in case the withdrawal sys-tem is removed from the container.The grounding of the container and the grounding of the withdrawal system must be installed before opening the container. The withdrawal system must remain grounded permanently.After finishing the work steps (emptying and closing the container completely) the grounding clamp of the container can be removed and used to ground the new container directly.The discharge of electrostatic charges of the user must be ensured. Therefore, the user must always wear conductive personal protective equipment, especially shoes and gloves. The floor has to be conductive as well.Safety notices - continued -Sampling vessels made of insulating material with a volume greater than 1 liter should not be used.Before using the withdrawal system, the user must ensure that there are no additional ignition hazards caused by process-specific parameters, such as increased ignitability of the substances due to changed en-vironmental conditions or when sampling in combination with highly charge-generating processes.The choice of the withdrawal system for the different products is the responsibility of the customer. We only gives recommendations. The system is not suitable for corrosive acids.Before removing the sampling system or in the event of prolonged interruption of the pouring process, and in all cases overnight, the container must be vented to zero pressure.Handling noticesThe withdrawal system at issue is designed for dispensing solvents from our stainless steel 10 l and 25 l drums with manual pressure build-up by a pump ball.The solvents container must be properly grounded before opening. Subsequently, the container lid is opened using a drum key (e. g. Cat. No. 1.08803.0001).For the first usage or after solvent exchanges the system has to be pre-rinsed (dip tube inside and outside) with a sufficient amount of the solvent to be used. The first milliliters should be discarded to avoid a transfer of possible production-related impurities into the solvent. After long shutdown times a flushing of the whole system is recommended.Ensure that the container is depressurized before the withdrawal system is removed. (see “Removal and installation of a new, full solvents drum”).When removing the withdrawal system from the container, ensure that the system is still grounded. Solvent residues inside the withdrawal system can be returned to the container via the dip tube by moving the stop-cock. The empty container must be closed immediately after removal of the withdrawal system.The ground should be removed only after the complete closure of the container!IMPORTANT: Ensure that the dip tube is not touched during the container-exchange procedure and that the withdrawal system is installed directly into the new container without putting it down on another sur-face.Withdrawal system for solvents with manualpressure build-up for 10 l and 25 l stainless steel drumsHandling and safety noticesWithdrawal system for solvents with manualpressure build-up for 10 l and 25 l stainless steel drumsHandling and safety noticesHandling notices - continued -Installation1.

apart.The deadband of each switch will be within the limits noted on the nameplate.Series LD-A switches may be set to operate with any dead-band within the limits shown on the nameplate.MOUNTINGThe “L ”Series ASHCROFT ®snap action differential pressure switch has a NEMA-4X enclosure which is an epoxy coated aluminum casting.T wo holes in the integral bracket are used to surface mount the control.Location of these holes is shown on the general dimension drawings.An optional pipe mounting bracket is also available.Mount on a vibration free surface or pipe in any orientation.PRESSURE CONNECTIONSFor operation as a differential pressure control – connect the high pressure to the side port marked “H”and the low pressure to the side port marked “L.”CONDUIT CONNECTIONSOne 3⁄4NPT hole fitted with a shipping plug, and two additional knock outs are provided.The knockouts may be removed by placing a screwdriver in the slot and rapping sharply with ahammer.It is recommended that T eflon tape or other sealant be used on conduit bushing or plug threads to ensure integrity of the enclosure.ELECTRICAL CONNECTIONRemove cover, held in place by two screws.On all units except one with terminal blocks – wire directly to the switch according to circuit requirements.Units with terminal blocks – wire directly to terminal blocks as required.T erminals are marked common (C), normally open (NO) and normally closed (NC).STANDARD RANGES 30, 60, 90, 200, 400 psid4.121/P R E LEFT SWITCH TERMINAL BLOCKRIGHT SWITCH TERMINAL BLOCKSERVICE LEADS TO THESE TERMINALSSETPOINT ADJUSTMENTSSetpoints are changed by means of the setpoint adjusters.The LD-S single switch has one adjuster and the LD-A adjustable deadband and LD-D dual switches each have two adjusters.On switches with two adjusters, the one on the left is referred to as “A”and the right one is referred to as “B”;see illustration.Setpoints can be adjusted from 20 to 100 percent of full range on increasing pressure.SERIES LD-S SINGLE SWITCHRemove cover.For setpoint adjustment on either increasing or decreasing pressure to within ±1% of nominal range, mount the switch on a calibration stand and use a suitable reference such as an ASHCROFT®Duragauge or test gauge.Monitor switch with a light or meter.Apply Low pressure.Then apply High pressure equal to the low pressure plus the differential pressure setpoint.If setpoint is on increasing differential pressure, turn adjuster so that switch operates (if common-normally closed circuit is being monitored light goes off).If setpoint is on decreasing differential pressure,turn adjuster so that switch resets (if common – normally closed circuit is being monitored light comes on).When the setpoint has been achieved, raise and lower the high pressure to ensure that the setpoint is correct.The deadband (difference between the operate and resetpressures) may be verified at this time to be between the values noted on the nameplate label.SERIES LD-D DUAL SWITCHRemove cover.For setpoint adjustment to within ±1% of nominal range, mount the switch on a calibration stand and use the suit-able reference such as an ASHCROFT ®Duragauge or test

About This GuideThis document is intended to provide guidance and cautions related to integrating an analog resistive touchscreen into an enclosure. The topics and suggestions contained within this document are taken from years of experience working with touchscreens. Remember, each situation is di erent and you may need to adjust some of the following suggestions to best fit your particular application and environment. Definitions and examples are provided to help illustrate good design practices. This document does not cover all the possible methods of touchscreen integration, but the general practices apply. Clearances and tolerances are typical with all Newhaven Display touch panels; see individual spec sheets for variances.Typical Analog Touch Panel ConstructionA resistive touch panel is constructed of 2 sheets of material separated slightly by a spacer. A common construction is a sheet of glass providing a stable bottom layer and a sheet of Polyethylene (PET) as a flexible top layer. The spacer may have openings to allow venting.The two sheets are coated with a resistive substance, usually a metal compound called Indium Tin Oxide (ITO). The ITO is thinly and uniformly sputtered onto both the glass and the PET layer. Nearly invisible bumps called spacer dots are then added to the bottom layer, on top of the resistive ITO coating. The bumps keep the PET film from sagging, causing an accidental or false touch. The amount of pressure needed to cause a "touch event" is largely determined by the size and spacing of the spacer dots.The Buss Bars and Traces, made of conductive silver ink, connect the ITO layer to the flex tail. The connection may be made with silver ink or a process similar to soldering called heat-seal. Silver ink is again used to connect the top traces to the bottom traces, as needed.Gaskets To help prevent dust and moisture, we recommend using a gasket between the touchscreen and the display. A gasket will also help cushion the touchscreen/display assembly from shock and vibration.Our Newhaven Display gasket uses a strong-bonding adhesive on the touch screen side and a low-bonding adhesive on the display side. We can ship the touch screen with the gasket pre-installed. The low-bonding adhesive on the display side allows for easier assembly and easier disassembly for rework or repair. Our Newhaven Display gasket provides the optimum spacing between the touchscreen and the display.If you should choose to use your own gasket, keep the following in mind.• Only use a high-bond adhesive on one side, if any. Strongly bonding both sides will make assembly and repair much more di icult.• For optimum viewing and to avoid "Newton Rings", spacing between the touchscreen and the display glass should be 0.2-0.5mm. Remember to take into account the thickness of the display's metal housing, if applicable.Mounting The Touchscreen To The Display Attaching the touchscreen to the display must be done in a dust-free environment (class 1000 clean-room) to prevent visible particles from becoming trapped between the touchscreen and the display. The light from the display can make dust particles glow brightly.When the PET film is presseddown, the two resistivesurfaces meet. The positionof this meeting (a touch) canbe read by a touchscreencontroller circuit.If the LCD has mounting holes and the touch screendoes not block these holes, the simplest method isto mount the LCD directly to the front bezel.Attaching The Touchscreen To The LCDMountingTouchscreens To The Housing BezelIf the LCD has no mountingholes or if the holes are blockedby the touchscreen, it'srecommended that a bracket beadded to the LCD for mounting.Screws, a clam shell capture arrangement,or other positive locking methods arerecommended to insure the touch panelstays in place a er repeated use. Mountingby adhesive alone is NOT recommended.Note in the 2 mounting examples, thedistance between the touchscreen andbezel is determined by a "hard top" betweenthe LCD panel (or bracket) and the bezel.DO NOT use gaskets or spacers on the front of the touch panel to regulate this gap. The gasket is there ONLY for appearance and to keep out dust and liquids. A large amount of pressure on the touch screen face may result in touch screen failure or inaccurate touches.We highly recommend using a foam gasket to prevent dirt or water from entering the enclosure. Even if you chose not to use a gasket, you must maintain the 0.3-0.7mm spacing between the face of the touch screen and the inner face of the bezel. Failure to keep this clearance may result in damage to the touch screen.Cautions and TolerancesThe figure to the right illustrates how touchesclose to the internal spacer can cause the toplayer to flex at a sharp angle, cracking the toplayer's resistive coating. This cracking may resultin reduced touch sensitivity or changes inlinearity. Avoid putting buttons or other touchfeatures within 2mm of the internal spacer.Preferably, design your system in such a way thata touch right next to the bezel is 2mm or morefrom the internal spacer.A. Bezel Edge to Active Area (Prevents false touches due to bezel flexing, dirt accumulation...etc)B. Bezel Edge to Viewable Area (Provides a cosmetically plesing bezel design)C. Bezel Inner Face to Touchscreen Top Layer (Prevents touchscreen from flexing or twisting due to imperfections in bezel inner face)D. Inner Gasket Edge to Viewable Area (Prevents false touches due to gasket pressing on flexible area of touchscreen)E. Outer Gasket Edge to Edge of Touchscreen Top Layer (Prevents electrical shorting due to gasket rolling over outer edge of touchscreen)* May need to increase to take into account gasket thickness, compression ratio and tolerance due to assembly limitations. A: 1.0mm (min)B: 0.8mm (min)C: 0.3 - 0.7mmD: 1.0mm (min) *E: 0.5mm (min) *Tail Handling Precautions The tail, while not fragile, can be damaged by improper usage and handling.1. Never Pick Up the Touch Screen by its TailThis includes when removing the touchscreen from its packaging. Holding by the tail can cause a lot of pressure on the junction of thetail and the touch screen an cause the touchscreen to fail.2. Avoid Twisting the TailTwisting the tail can place considerable stress where the tail meets the touchscreen. 3. Avoid Touching the Tail Conductors Touching the tail conductors may contaminate them. This could result in reduced sensitivity or even corrosion.Tail Design Considerations1. Tail Bend and TwistTail bend radius is 3mm minimum. Design the system to avoid creasing the tail. Avoid twisting the tail. While the tails are very durable,bends and twists can put considerable pressure on the tail and the tail-touchscreen junction.2. Strain ReliefNo strain relief is required as long as the bend radius at the touch screen is 3mm. The tail should not place any tension on the top film layer.3. NoiseTry to avoid routing the tail near any electrically noisy areas such as backlights, high energy coils..etc. The tail could act as an antenna and the noise may reduce sensitivity or give inaccurate touch results.Tail Considerations and Cautions。
