Hi Sir,

 

Our design is in production phase. We are facing a critical issue during the testing. We need your support.

 

PFA power supply design. 12V input to 5V output.

Issue we have observed is that between two consecutive power ON/OFF cycle with lesser duration the board does not work.

 

Channel 1 is 5V output from regulator. If more time is provided between two power ON/OFF cycle the board works.
