Hello, I would like to ask a question.
I recently learned UCD3138 full bridge hard switch development board, how to achieve UCD3138 synchronous output and synchronous input switching frequency? Is there a relevant design case?
Thank you!

HI,

I believe you are talking about synchronizing the switching frequency to an external PWM input . Is this correct ?
If so , there is already a post on that .Please take a look at this post :
