UCD3138 PSFB EVM27开发板欠压保护问题

Other Parts Discussed in Thread: UCD3138

您好。

我最近测试了UCD3138 PSFB EVM27开发板欠压保护功能。

我看源代码上:

#define VIN_ON (346)//translated(2674)
#define VIN_OFF (340)//translated (2630)
#define VIN_UV_FAULT_LIMIT (346)

我尝试修改了Vin的欠压关断点,我想从340V关断调整到335V。我修改了代码。

#define VIN_OFF (335)//

可再次调试时,发现欠压关断点还是在340V,我不知道还需要更改什么地方,才可以降低欠压关断点。

谢谢。
