LG IG5 3.7KW---2.2KW 380V故障：一般LG的故障由主板引起的有无显示、电位器调不了速、通讯故障等。

在驱动板是好的情况下，主板引起故障的维修方法分析及排除如下：1.无显示故障排除方法无显示一般除底版和开关电源引起故障，主板也经常出现无显示的，办法是先找排插，万用表测量与好的主板对比参数，大多数与3个R271（电阻）的线路扩展找，有很多电阻烧坏的，比如查找R1R3R4R7R812R16R18R19R20R21R22R49等。

主板U2（IC3404）也会引起无显示的，还有震荡器和U10（31AKDS75176BM、MEACDS75176BM）及旁边的电阻损坏也是无显示或者报OC、OU、OH，由于主板一个电阻都有可能一起故障。

2.电位器调不了参数排除方法：先检查光藕PC2.PC3.PC4，如果测量它们的参数相同（不能超过正负5的误差，否则就要换新的），这样在换U9（788J），换上788J后，上电会显示0.00，这个时候，当自己设置好50.00H后，测量输出是否平衡，平衡了在带电机。

如果发现U、V、W、有一项没有输出电压，应该检查光藕PC14、PC15、PC17这三个，它们型号是（5F112A）量下他们参数是与好的主板是不是一样，如果不同就换新的光藕。

大多数换上后输出电压都会正常，有时候还要换U5（33EE7TK、37DL38KLS06、51AJ8HK、57A81RKLS06）换好后这样就会和新的机器运转一样，没有任何瑕疵和不正常的运行声音。

3. 大多主板引起通讯故障报警IOLE，检查电路板是不是有氧化或者被腐蚀的焊脚，电路短路的情况，由于U1（2901）经常会内部线路故障也会报IOLE，其一是更换新的IC，也可以拆坏板应对故障，U1（2901）旁边的电阻与CPU连接线路和CPU周围的电阻是否损坏，以上是LG经常出现的复杂故障。

LG主板大多都通用，我强调在维修时，更换光藕和IC时，看好型号，2.2KW与3.7KW 的IC及光藕有很大区别，在同型号的情况下可替换，反之就是明明换了好的器件也解决不了根本问题。

All rights reserved. is a registered trademark of Richtek Technology Corporation.Application InformationThe RT8511B is a current mode boost converter which operates at a fixed frequency of 500kHz. It is capable of driving up to 10 white LEDs in series and integrates functions such as soft-start, compensation, and internal analog dimming control. The protection block also provides over-voltage, over-temperature, and current- limit protection features.LED Current SettingThe loop structure of the boost converter keeps the FB pin voltage equal to the reference voltage V FB . Therefore,by connecting the resistor, R SET between the FB pin and GND, the LED current will be determined by the current through R SET . The LED current can be calculated by the following equation :FBLED SET VI = R Brightness ControlFor the brightness dimming control of the RT8511B, the IC provides typically 200mV reference voltage when the PWM pin is constantly pulled high. However, the PWM pin allows a PWM signal to adjust the reference voltage by changing the PWM duty cycle to achieve LED brightness dimming control. The relationship between the duty cycle and the FB voltage can be calculated according to the following equation :V FB = 200mV x Dutywhere 200mV is the typical internal reference voltage and Duty is the duty cycle of the PWM signal.As shown in Figure 3, the duty cycle of the PWM signal is used to modify the internal 200mV reference voltage.With an on-chip output clamping amplifier and a serial resistor, the PWM dimming signal is easily low-pass filtered to an analog dimming signal with one external capacitor, C DIMC , for noise-free PWM dimming. Dimming frequency can be sufficiently adjusted from 100Hz to 8kHz.However, the LED current cannot be 100% proportional to the duty cycle. Referring to T able 1, the minimum dimming duty can be as low as 1% for the frequency range from 100Hz to 8kHz. It should be noted that the accuracy of 1% duty is not guaranteed.Figure 3. Block Diagram of Programmable FB Voltage Table 1. Minimum Duty for Dimming FrequencyBecause the voltage of DIMC and FB is small to 2mV andeasily affected by LX switching noise.ToControllerThe FB pin voltage will be decreased by lower PWM duty ratio . That will achieve LED current diming function for different brightness. But LED current is more accurate when higher PWM duty. The Table 2. shows typical variation value comparison between different PWM duty and condition is V IN = 3.7V, LED array = 6S2P , R SET =5Ω.Table 2. LED Current Variation vs PWM DutyIt also should be noted that when the input voltage is too close to the output voltage [(V OUT −V IN ) < 6V] , excessive audible noise may occur. Additionally, for accurate brightness dimming control, the input voltage should be kept lower than the LEDs' turn on voltage. When operating in the light load, excessive output ripple may occur.RT8511B8DS8511B-05 February 2015 ©Copyright 2015 Richtek Technology Corporation.

Power Off SequenceV INV OUTENV INV OUTENPWMV INV OUTENPWMV INV V INV OUTENPWMDelayMode1V INV ENSoft-StartThe RT8511B provides a built-in soft-start function to limit the inrush current, while allowing for an increased PWM frequency for dimming.Current Limiting ProtectionThe RT8511B can limit the peak current to achieve over current protection. The IC senses the inductor current through the LX pin in the charging period. When the value exceeds the current limiting threshold, the internal N-MOSFET will be turned off. In the off period, the inductor current will descend. The internal MOSFET is turned on by the oscillator during the beginning of the next cycle.Power SequenceIn order to assure that the normal soft-start function is in place for suppressing the inrush current, the input voltage and enable voltage should be ready before PWM pulls high. Figure 4 and Figure 5 show the power on and power off sequences.RT8511B9DS8511B-05 February 2015©Copyright 2015 Richtek Technology Corporation.

The OTP will shut down switching operation if the junction temperature exceeds 160°C. The boost converter will start switching again when the junction temperature is cooled down by approximately 30°C.Inductor SelectionThe inductance depends on the maximum input current.As a general rule, the inductor ripple current range is 20%to 40% of the maximum input current. If 40% is selected as an example, the inductor ripple current can be calculated according to the following equation :OUT OUTIN(MAX)(MIN)IN(MIN)RIPPLE IN(MAX)V I I =V I = 0.4I η⨯⨯⨯where η is the efficiency of the boost converter, I IN(MAX) is the maximum input current, I OUT is the total current from all LED strings, and I RIPPLE is the inductor ripple current.The input peak current can be calculated by maximum input current plus half of inductor ripple current shown as following equation :I PEAK = 1.2 x I IN(MAX)Note that the saturated current of the inductor must be greater than I PEAK . The inductance can eventually be determined according to the following equation :Over Voltage ProtectionThe RT8511B equips Over Voltage Protection (OVP)function. When the voltage at the OVP pin reaches a threshold of approximately 1.2V , the MOSFET drive output will turn off. The MOSFET drive output will turn on again once the voltage at the OVP pin drops below the threshold.Thus, the output voltage can be clamped at a certain voltage level, as shown in the following equation :()())2IN OUT IN 2OUT OUT OSCV (V V L =0.4V I f η⨯⨯-⨯⨯⨯where f OSC is the switching frequency. For better efficiency,it is suggested to choose an inductor with small series resistance.Diode SelectionThe Schottky diode is a good choice for an asynchronous boost converter due to its small forward voltage. However,when selecting a Schottky diode, important parameters such as power dissipation, reverse voltage rating, and pulsating peak current must all be taken into consideration. A suitable Schottky diode's reverse voltage rating must be greater than the maximum output voltage,and its average current rating must exceed the average output current.Capacitor SelectionTwo 1μF ceramic input capacitors and two 1μF ceramic output capacitors are recommended for driving 10 WLEDs in series. For better voltage filtering, ceramic capacitors with low ESR are recommended. Note that the X5R and X7R types are suitable because of their wide voltage and temperature ranges.Thermal ConsiderationsFor continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125°C. The junction to ambient thermal resistance, θJA , is layout dependent. For WDFN-8L 2x2 package, the thermal resistance, θJA , is 120°C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A = 25°C can be calculated by the following formulas :RT8511B10DS8511B-05 February 2015 ©Copyright 2015 Richtek Technology Corporation.

PCB Layout GuideLayout ConsiderationFor high frequency switching power supplies, the PCBlayout is important to obtain good regulation, high efficiency and stability. The following descriptions are the suggestions for better PCB layout.❝Input and output capacitors should be placed close to the IC and connected to the ground plane to reduce noise coupling.❝The GND and Exposed Pad should be connected to a strong ground plane for heat sinking and noise protection.❝The components L, D, C IN and C OUT must be placed as close as possible to reduce current loop. Keep the main current traces as possible as short and wide.❝The LX node of the DC/DC converter experiences is with high frequency voltage swings. It should be kept in a small area.❝The component R SET should be placed as close as possible to the IC and kept away from noisy devices.Figure 6.

RS485典型电路经典1 概述RS-485建议性标准作为⼀种多点差分数据传输的电⽓规范，现已成为业界应⽤最为⼴泛的标准通信接⼝之⼀，这种通信接⼝允许在简单的⼀对双绞线上进⾏多点双向通信，它所具有的噪声抑制能⼒、数据传输速率、电缆长度及可靠性是其他标准⽆法⽐拟的，因此许多不同领域都采⽤RS-485作为数据传输链路，它是⼀种极为经济并具有相当⾼的噪声抑制、传输速率、传输距离和宽共模范围的通信平台。

RS-485是⼀种在⼯业上作为数据交换的⼿段⽽⼴泛使⽤的串⾏通信⽅式，数据信号采⽤差分传输⽅式，也称作平衡传输，因此具有较强的抗⼲扰能⼒。

它使⽤⼀对双绞线，将其中⼀线定义为A ，另⼀线定义为B 。

通常情况下， RS-485的信号在传送出去之前会先分解成正负对称的两条线路（即我们常说的A 、B 信号线），当到达接收端后，再将信号相减还原成原来的信号。

发送驱动器A 、B 之间的正电平在+2～+6V ，是⼀个逻辑状态；负电平在-2～-6V ，是另⼀个逻辑状态；另有⼀个信号地C ，在RS-485中还有⼀“使能”端。

“使能”端是⽤于控制发送驱动器与传输线的切断与连接。

当“使能”端起作⽤时，发送驱动器处于⾼阻状态，称作“第三态”，即它是有别于逻辑“1”与“0”的第三态。

接收器也与发送端相对的电平逻辑规定，收、发端通过平衡双绞线将AA 与BB 对应相连，当在接收端AB 之间(DT)＝(D+) - (D-)有⼤于+200mV 的电平时，输出正逻辑电平，⼩于-200mV 时，输出负逻辑电平。

接收器接收平衡线上的电平范围通常在200mV ⾄6V 之间。

该应⽤现已经被⼴泛⽤于公司批控仪，R7系列产品的485通讯。

Z LF2 主要性能指标DS75176B 芯⽚技术性能指标：供电电压范围：4.75V to 5.25V ；接收输⼊阻抗：12K ；最⼤接收器数量：32个；共模输⼊电压范围：-7V to 12V ；滞回电压：70mV ；关键芯⽚管脚说明：RE 管脚：接收器输出使能（低电平有效）。

LG IG5 3.7KW---2.2KW 380V故障：一般LG的故障由主板引起的有无显示、电位器调不了速、通讯故障等。

在驱动板是好的情况下，主板引起故障的维修方法分析及排除如下：1.无显示故障排除方法无显示一般除底版和开关电源引起故障，主板也经常出现无显示的，办法是先找排插，万用表测量与好的主板对比参数，大多数与3个R271（电阻）的线路扩展找，有很多电阻烧坏的，比如查找R1R3R4R7R812R16R18R19R20R21R22R49等。

主板U2（IC3404）也会引起无显示的，还有震荡器和U10（31AKDS75176BM、MEACDS75176BM）及旁边的电阻损坏也是无显示或者报OC、OU、OH，由于主板一个电阻都有可能一起故障。

2.电位器调不了参数排除方法：先检查光藕PC2.PC3.PC4，如果测量它们的参数相同（不能超过正负5的误差，否则就要换新的），这样在换U9（788J），换上788J后，上电会显示0.00，这个时候，当自己设置好50.00H后，测量输出是否平衡，平衡了在带电机。

如果发现U、V、W、有一项没有输出电压，应该检查光藕PC14、PC15、PC17这三个，它们型号是（5F112A）量下他们参数是与好的主板是不是一样，如果不同就换新的光藕。

大多数换上后输出电压都会正常，有时候还要换U5（33EE7TK、37DL38KLS06、51AJ8HK、57A81RKLS06）换好后这样就会和新的机器运转一样，没有任何瑕疵和不正常的运行声音。

3. 大多主板引起通讯故障报警IOLE，检查电路板是不是有氧化或者被腐蚀的焊脚，电路短路的情况，由于U1（2901）经常会内部线路故障也会报IOLE，其一是更换新的IC，也可以拆坏板应对故障，U1（2901）旁边的电阻与CPU连接线路和CPU周围的电阻是否损坏，以上是LG经常出现的复杂故障。

LG主板大多都通用，我强调在维修时，更换光藕和IC时，看好型号，2.2KW与3.7KW 的IC及光藕有很大区别，在同型号的情况下可替换，反之就是明明换了好的器件也解决不了根本问题。
