Other Parts Discussed in Thread: TPS2373 TPS2373-4RGWR(TI)这一颗芯片在做PD测试的时候出现了Inrushl 2指标warming,门限400mA,测试出来402--405mA,请帮忙给出处理意见,附件是测试数据以及原理图,感谢。 2018.POE.pdf
手册上是这样解释的:
If the I AV(dem) signal increases, for example in response to an AC line voltage or load change then the average output of the A1 amplifier initially decreases by the same amount. The PWM duty cycle, and inductor current, will then increase because…
