Hi,

Doing output short circuit condition, when shorted output 1, the output 2 will be protected as well, is this normal?

Thank you.

Hello,

Is LM25199 working at 2phase configuration" or "single phase, dual output" configuration?

Thanks

Qian

Hi Chentsu,

Can you check the voltage of UVLO pin and EN2 pin, see if ch2 is turned off by these two pins?
Also, can you provide the schematic in pdf file for review?

Thanks
Qian
