Tool/software:

Hi team,

I have a question regarding the constant design of the synchronous rectifier circuit in the post-main transformer stage shown in the diagram below.

My customer is designing the circuit with reference to the UCC27714EVM-551.

Since it is a synchronous rectifier circuit, is it acceptable to use the same settings as the EVM for the constants?

Or is there a formula to determine the constants?

Best regards,

Kyohei
