Dear Sir
Many thanks for you reply,
we met some issue that we test our board(reference PMP1360 Vout :12V/1A). when we power source to use adapter in. then output voltage start up is normal.
But when we power source use PSE, then output start up sometime normal. but sometimes output will steady 4.5V a few seconds then reach to normal 12V.
May you pls have some suggestion to us for debug?
Best regards,
Bogey
