Hi All,

We have developed a AC-DC & DC-DC Board. We are having an issue of Voltage Drop when the load is connected to the board. There is drastic voltage variation in the board. It would be helpful if you can support for the same asap.POWER-CARD.pdf

Hi SW

Please check that the voltage on the COMP pin is going high, to 5V and also check the voltage on the CS pin to ensure it is less than 1V peak or else the controller will start to reduce on time of the mosfet to limit the peak current.

Regards

Peter

Hi SW,

I hope you have made some progress in the meantime, since there has been no activity on this post I am going to close it.

Please open a new post if you have more questions.
