首先，我们来了解一下yx4305a的基本结构。

yx4305a由相位频率控制器（PFC）、数字控制振荡器（DCO）、两个分频器（Divider）、两个锁相环（PLL）和多路动态选择器（MUX）等主要部件组成。

接下来，我们来逐步解析yx4305a的工作原理。

首先，外部输入信号进入PFC，PFC负责提取输入信号的频率和相位信息，并将其与设定值进行比较。

根据比较结果，PFC产生控制电压，通过控制电压来调节DCO的频率。

DCO是yx4305a最重要的部件之一，它负责产生基准信号和参考信号。

DCO通过控制电压来调整其频率，以跟随输入信号的频率变化。

其频率可以通过PWM（脉宽调制）信号来控制。

接下来，基准信号和参考信号进入PLL。

PLL起到锁定频率和相位的作用。

首先，基准信号经过第一个PLL进行频率的倍频和除频，产生参考信号。

参考信号经过第二个PLL进行相位锁定，以同步输入信号的相位。

最后，经过锁相环的输出信号进入MUX。

MUX的作用是选择输出信号的路径，将其传递给需要的设备或部件。

以上就是yx4305a的基本工作原理。

Sequence ChartTPS65552A has one internal enable latch,F1,that holds a charge(ON/OFF status)of the device.See Figure2. The only way to start charging is to input CHG↑(see time A/C/H in Figure4).Each time CHG↑is reached,the TPS65552A starts charging.There are three trigger events to stop charging:1.Forced stop by inputting CHG=L from the controller(see timeB in Figure4).2.Automatic stop by detecting full charge.VOUT reaches the target value(see TimeD in Figure4).3.Protected stop by over V DS detection(see TimeI in Figure4).When the charging operation is completed,the TPS65552A drives the charge completion indicator pin,XFULL, to GND.XFULL is an open-drain type output.When connecting the indicator LED to XFULL,the LED lights are on when fully charged.The controller detects the status of the device as a logic signal when connecting a pullup resister,R1(see Figure1).XFULL enables the controller to detect the over V DS protection status using software time.If over V DS protection occurs,XFULL never goes L during CHG=H,provided that the timer that starts at CHG↑stops at XFULL↑,and times out within a designed period of maximum charging times.The controller can detect over V DS at time out. The device starts charging at timeH,and over V DS protection occurs at TimeI(see Figure4).At timeI,XFULL stays H,and the controller detects over V DS protection when the timer ends at timeJ.the controller inputs CHG=L to terminate the operation.6P R O D U C T P R E V I E WVVIISWCHGI Control Chargingt = L ON I P E A K V B A T ÷÷øöççèæ(1)TPS65552ASLVS567–JULY 2005Figure 5.Timing Diagram at One

(SW)exceeds I (PEAK)turns OFF (Time2in Figure 5).When SW turns OFF (Time2in Figure 5),the magnetic energy in the transformer starts discharging.Meanwhile,U2monitors the kickback SW terminal.As the energy is discharging,the kickback voltage is increasing according to the increase of V OUT (Time2to Time3in Figure 5).When almost all energy is discharged,the system cannot continue rectification via the diode,and the current of I OUT goes to zero (Times3in Figure 5).After rectification stops,the small amount of energy left in the transformer is released via the parasitic the kickback voltage reaches zero (Time3to Time4in Figure 5).During this period,U2makes SW turn ON when (V (SW)-VBAT)dips from V (ZERO)(Time5in Figure 5).circuit,the period between Time4and Time5in Figure 5is small or does not appear the delay time of the U2detection to SW ON.U1also monitors the kickback voltage.When (V (SW)-VBAT)exceeds V (FULL),TPS65552A stops charging (see Figure 6).In Figure 5and Figure 6,ON time is always the same period in every switching.The ON time is calculated by Equation 1This is not dependent on output voltage.However,OFF time is dependant on output voltage.As the output voltage gets higher,the OFF time gets shorter(see Equation 2).7PRODUCT PREVIEW t= N_TURN x LOFFIPEAKVOUT÷÷øöççèæ(2) Reference VoltageTermination Voltage SettingTPS65552ASLVS567–JULY2005The TPS65552A does not have its own reference voltage circuit inside,and the TPS65552A uses the VCC input voltage as a reference to detect I(PEAK),V(ZERO),and V(FULL).Therefore,voltage input at VCC is approximately 5V.VCC differs from5V by system limitations.Table1shows the dependence of each function of TPS65552A to VCC.Table1.VCC Dependence of TPS65552APARAMETER EQUATION VCC4.555.5I(PEAK1)0.52x VCC-0.92 1.42 1.68

terminal.Figure 7shows how to program I (PEAK).I_PEAK input is treated as a logic input,when its voltage is below V (PKL)(0.6V)and above V (PKH)(2.4V).Between V (PKL)and V (PKH),I_PEAK input is treated as an analog ing this characteristic,I (PEAK)can be set by the logic signal or by an analog input.Typical usages of this function are:1.Charging I (PEAK)depends on the battery rge I (PEAK)for an adequate battery,small I (PEAK)for a poor battery.2.Reducing I (PEAK)when zooming lens (motor works);this avoids shutdown of the battery with a large current output.In Figure 1,three optional connections to I_PEAK are shown.e the controller to treat I_PEAK as the logic input pin.This option is the easiest.e a D/A converter to force I (PEAK)to follow analog information,such as battery voltage.e an analog circuit to achieve the same results as the D/A converter.Figure 7.I_PEAK vs I (SW)The IGBT driver provided by the TPS65552A is a simple buffer in the logical table.Table 3shows the function (see Figure 4).Table 3.IBGT Driver Function TableF_ON G_IGBTL L HH9PRODUCT PREVIEW ProtectionsThermal ShutdownMAX ON TimeOvervoltage at Power SWPCB InformationTPS65552ASLVS567–JULY2005TPS65552A provides three protections:thermal shutdown,max on time,and overvoltage at power SW.When TPS65552A overheats,all functions stop.The only way to recover is to wait for the TPS65552A to cool down.This protection is not through SHUTDOWN,so the TPS65552A restarts charging if CHG stays H during the whole overheated period.To prevent a condition such as pulling current from a poor power source(i.e.,an almost empty battery),the TPS65552A provides a maximum ON time protection.If the ON time exceeds t MAX,the TPS555x is forced OFF regardless of I(PEAK)detection.To avoid the stress of power dissipation,the TPS65552A provides an overvoltage monitor function at the SW terminal.If this protection occurs,the overvoltage status is latched(see Figure4and its descriptions).This function also protects short-circuit of the secondary side.In the short-circuit state of the secondary side, almost100%of the battery voltage is supplied to SW,which stresses the device.Figure8.PCB Design Guideline10P R O D U C T P R E V I E WAdditional Technical InformationTPS65552ASLVS567–JULY 2005Figure 8shows key points when designing a PCB.1.In many DSC designs,parasitic resistance that cannot be ignored,exists on the power line path from the battery to the primary side turn of the transformer.The TPS65552A has one ground point connection inside the IC at the PGND PAD.So,the PCB layout should also keep a one-point ground connection at the PGND terminal of TPS65552A.2.The loop indicated by dotted-lines is laid out as small as possible to reduce the open area of the loop.3.The TPS65552A uses the VCC input as a reference voltage.Considering Note 1,the ground of the power unit that sources VCC is connected to PGND.4.Regarding Note 3,the bypass capacitor,C2,is required to avoid grounding noise.TI provides an application note for this device.For more technical information,please find the application note on the TI Web site or consult your

当C808的电压达到启动开始电压VCC （on ）=18V 时，STR-W6553A 开始工作，开关管开始有开关动作。

随着输出电压和辅助绕组电压的上升，由辅助绕组给IC 供电。

1、关于启动①由于IC 的启动电流很小，R803可使用高阻值的电阻，来降低待机功耗。

但是要注意R803要向IC 提供足够的锁定电路保持电流，特别是低电压输入的时候能向IC 提供100UA 以上的电流。

ON/OFFSequenceThe enable/disable of each channel is controlled by logic input signals level at XSLEEP (pin 7for all channels),ENAFE (pin 6for CH4),EN56(pin 46for CH5and CH6)and EN7(pin 8for CH7).Table

(2)State 10(CH8:PFM mode)must go through State 2.This device has the power ON/OFF sequence of CH1/2/3/8/REF and CH5/6for DSC application.The CH1/2/3/8/REF sequence is shown in Figure 1.The CH5/6sequence is shown in Figure 2.CH4and CH7have individual sequences but CH4/5/6has relationship with CH1/2/3slope of soft start is the same and puts high priority of CH1/2/3to avoid the functional conflict (see the Soft Start description).Due to this,CH4/5/6should not be ON before CH1/2/3is ON.When XSLEEP is forced low,all channels turn OFF with the power OFF sequence.Figure

device has two slopes,defined by S/S (pin 9)and S/S56(pin 45).The slopes of CH1/2/3/4are defined by S/S (pin 9);the slope of CH5/6depends on SEQ56(pin 47)signal level.When SEQ 56(pin 47)is low,the slope of CH5is defined by S/S (pin 9),the slope of CH6is defined by S/S56(pin 45).When SEQ 56(pin 47)is high,the slopes of CH5and CH6are defined by S/S56(pin 45).The soft-start time is calculated by

level at V CC2(pin 12).When XSLEEP is high and V CC2(pin 12)is less than the threshold (defined in Electrical Characteristics as UVLO detect level),the operation shuts down immediately without the power OFF sequence.UVLO has a hysteresis as shown in Figure 3.This factor is defined in Electrical Characteristics as UVLO hysteresis.Figure 3.UVLO HysteresisThe TPS65530has protections:overcurrent

topology.CH1/3is the voltage-mode-controlled synchronous buck converter for engine core (CH1)or external memory (CH3).Both high-side and low-side switches are integrated into the device and consist of NMOS-FET only.The gate of the high-side switch is driven by bootstrap circuit.The capacitance of the bootstrap is included in the device.These channels are able to operate up to 100%duty cycle.This device has a discharge path to use the switch (Q_Discharge1/3)for CH1/3output capacitor via the inductor.The switch is activated after the power OFF sequence has started.Typical resistance at the discharge circuit is 1k Ω.When the device detects the threshold at FB1/3after the power OFF sequence has started,the MOSFET turns OFF and the output is fixed with high impedance.It is acceptable to connect the battery to V CC1(pin 18)/V CC3(pin 23)directly when the battery voltage is more than 2.5V.When the battery voltage is less than 2.5V,the CH8output should be connected to V CC1(pin 18)/V CC3(pin 23).The output voltage is programmed from 0.9V to 2.5V (both CH1and CH3)to use the feedback loop sensed by the external resistances.The output voltage is calculated by Equation 5.The block

converter for engine I/O(CH2)or AFE(CH4).This converter is an adapted H-bridge circuit to use four switches.These switches are integrated into the device and consist of NMOS-FET only.The gate of the high-side switch is controlled by the bootstrap circuit.The capacitance of the bootstrap is included in the device. The device automatically switches from buck operation to boost operation or from boost operation to buck operation as required by the configuration.It always uses one active switch,one rectifying switch,one switch permanently on,and one switch permanently off.Therefore,it operates as a buck converter when the input voltage is higher than the output voltage,and as a boost converter when the input voltage is lower than the output voltage.There is no mode of operation in which all four switches are permanently switching.This device has a discharge switch(Q_Discharge2/4)for the CH2/4output capacitor.The typical ON resistance at the discharge switch is1kΩ.The discharge switch is activated when XSLEEP turns low.For CH4only,the switch is also activated when ENAFE turns low.After output voltage reaches approximately0.5V,the discharge switch turns OFF and VOUT2/4is changed into high impedance.The output voltage is programmable from2.5V to3.6V(for CH2)or from2.2V to3.6V(for CH4)to use the feedback loop sensed by the external resistances. The output voltage is calculated by Equation6.The block diagram is shown in Figure5.V OUT=(1+R2/R1)×0.6[V](6) V OUT:Output voltage[V] R1,R2:Feedback resistance(see Figure5)Figure5.CH2/4Block Diagram。

硬盘盒主控芯片介绍元谷选元谷刀锋不如选元谷星钻iPD-USB 2.5寸串口SATA 移动硬盘盒元谷PD2500也可以元谷的做工没得挑，最关键得是看一下内部芯片。

一些主流硬盘盒芯片介绍IDE芯片：68300A/B/C赛普拉斯公司最出名的芯片，由原ISD公司的经典产品ISD300A 控制芯片二次开发得来，用于2.5及3.5系列IDE设备，优点是兼容性好，故障率低，缺点是偶尔会供电不足现象，元谷公司早期采用68300B的PD2500盒子就出现过此类问题，68300C得到较好改善。

经典的有：元谷PD2500、奈雷特D2/D4、瀚士威H570C、H560C等。

后期好一点的盒子USB线上都带双接头取电。

友情提示：赛普拉斯公司目前还没推出支持SATA硬盘的芯片，所以请不要开口赛普拉斯、闭口赛普拉斯。

INITIO 1511美国英尼硕公司主推的IDE控制芯片，各项技术指标都可以赛普拉斯芯片，但主要是价位较高，况且受产能限制，在市面上见的不多。

元谷刀锋2500IDE采用此款芯片。

NT68320 BE/GP图美自有芯片，图美是目前国内唯一能研发控制芯片的硬盘盒厂商，技术实力可见一斑，BE为备份型，GP为高速型。

整体评价介于PL-2506和68300之间。

NEC D720133GB这个不用多说，NEC的牛X芯片，性能速度兼容性绝对一流，但是价格也是一流。

我目前的产品线只有微星原装V3使用的是这款芯片，不过后期我估计也要换掉，因为只能支持IDE硬盘，不利于工厂控制成本，现在IDE笔记本盘比SATA盘要贵的多。

PL-2506旺玖公司的主要产品，价位中下，兼容性不错，功耗控制也较好，图美U225X就是采用这款芯片。

M110 台湾奇岩公司的得力产品，众多知名厂商选用，通用性强，1.8寸-5.25寸IDE设备通吃，性能不错。

缺陷还未发现。

蓝硕的USB易驱就是用的M110。

GL811/811E科X等杂牌用的最多的芯片，价格低廉，参数一般。

TPS5430电源应用方案一、芯片概述TPS5430有着宽输入电压，低静态功耗，转换效率高，实际应用十分广泛。

基本性能参数如下所示。

1.输入电压范围：5.5～36V2.输出电压可调节3.转换效率最高可达到95%。

4.输出持续电流达3A，峰值电流可达4A。

5.关断模式仅消耗18uA电流。

6.工作温度：-40～125℃二、电路设计电路设计参数要求（输入电压范围:10.8～19.8V;输出电压:5V;输入波纹电压:300mV;输出波纹电压:30mV;输出额定电流:3A）。

本人针对芯片资料进行电源电路部分设计，原理图如2-1所示。

芯片引脚ENA端为电源使能控制端，通过MCU来控制，在需要的时候开启电源，不需要时关闭电源，以降低系统功耗。

图2-1三、电路板设计由于电源设计关系到整个系统命脉，在设计电路板布线和元件放置时，严格按照芯片资料要求进行。

在芯片正下方应放置焊盘连接到电源地(GND)，并打好过孔。

如图3-1所示。

其元件选择也要求也比较严格。

①输入电容。

TPS5430输入需要一个稍大些的退耦电容。

这里推荐100uF和0.1uF（C60、C61）的贴片铝电解电容和高性能陶瓷电容。

也可以选择小一点的电容，但要满足输入电压和额定电流波纹要求。

②输出滤波器件。

输出滤波器件，即L8、C62。

TPS5430具有内部补偿电路。

输出电感与最大输出电流有关，这里选择15uH电感。

输出电容是影响额定电压、额定波纹电流和等价阻抗（ESR）的重要设计因素。

此应用中选择100uF输出电容，此时电路中产生的RMS波纹电流为143mA, 需要最大的ESR为40MΩ。

③输出电压设置。

输出电压由反馈控制脚FB脚的精密电阻（R55、R57、R56、R54）决定。

如果输出电压5.0V，参考电压1.221V，R1为10kΩ，则确定R2为3.24kΩ。

④ BOOT （启动）电容。

BOOT电容C62选择0.01uF。

⑤捕获二极管。

TPS5430需要外部捕获二极管，选择B340A，它的反向电压为40V，正向电流3A，正向电压0.5V。

tps63070rnmr 输出电压低于2.5v的原因-回复tps63070rnmr是一种高效的降压稳压器，其输出电压低于2.5V可能有几个原因。

在本文中，我将一步一步回答这个问题，并解释每个原因。

1. 输入电压不足：tps63070rnmr是一款输入电压范围广泛的稳压器，但如果输入电压低于其工作电压范围，输出电压将低于2.5V。

这可能是由于电源问题、电池电量不足或错误的输入电压设置等引起的。

通过正确检查和调整输入电压，可以解决这个问题。

2. 输出负载过重：tps63070rnmr有一个最大负载限制，如果连接到该稳压器的负载超过其额定负载范围，输出电压可能下降到低于2.5V。

这种情况可能是由于负载本身要求更高的电流或错误连接的问题引起的。

应该根据负载的需求和稳压器的规格来选择合适的负载，并确保正确连接。

3. 温度影响：tps63070rnmr对温度敏感，高温环境可能导致输出电压低于2.5V。

在高温环境中，稳压器的效率可能降低，电子元件的性能可能受到影响。

此外，高温也可能导致过热保护触发，使稳压器停止运行。

通过提供适当的散热和确保稳压器工作在合适的温度范围内，可以避免温度影响。

4. 错误的反馈电压设置：tps63070rnmr的反馈电压设置决定了其输出电压。

如果反馈电压设置错误，输出电压可能低于2.5V。

这可能是由于电路板设计错误、误选的反馈电阻或其他反馈元件问题引起的。

通过检查和调整反馈电压设置，可以解决这个问题。

5. 其他故障：除了上述原因外，tps63070rnmr的输出电压低于2.5V可能还有其他故障导致，如元件老化、损坏或不良的电源线路等。

在这种情况下，需要对稳压器进行彻底的故障排除，检查并修复潜在的问题。

总之，tps63070rnmr输出电压低于2.5V可能是由于输入电压不足、输出负载过重、温度影响、错误的反馈电压设置或其他故障导致的。

通过仔细检查和逐一解决这些问题，可以确保稳压器正常工作并输出符合要求的电压。
