Hello,

I am just wondering if UCC24624 can only be used in center tapped topology in LLC and it can not be used in voltage doubler. Because it only has one shared source sense pin VSS. Thank you very much.

Best,

Hao

Can you please show your voltage doubler configuration so we can understand where you intend to use UCC24624?

Hello,

I would like to use it for the secondary side to replace the two diodes as shown above. Thank you very much.

This configuration cannot use UCC24624 since UCC24624 does not have high side driver.

Can you look at UCC24612 to see if it fits this application?
