Part Number: LMR38020LMR38020的输入VIN和EN引脚直接接在一起;LMR38020输入回路有添加一个pmos做为输入控制的开关,此pmos会有漏电导致LMR38020的模块下电时候(pmos关闭),LMR38020的输入VIN和EN引脚依然有1.2V左右的电压。
帮忙分析一下什么情况会出现LMR38020输出锁住,即使重新上下电依然无法恢复,除非是下电时将LMR38020的输入VIN和EN引脚的1.2V左右的电压泄放才能恢复。

Part Number: LMR38020 Hi,
I used LMR38020 for a DC-DC flybuck converter with 3 outputs, two of them being not isolated(3.3V/1.5A and 12V/200mA), one of them being isolated(12V/100mA). But the 3.3V output voltage ripple is very large at full load, how should…

Hi,
I would like to use LMR38020 for a DC-DC flybuck converter with 3 outputs, two of them being not isolated(3.3V/1.5A and 12V/200mA), one of them being isolated(12V/100mA). But I meet some trouble. LMR38020.tif
