UCC24612: Synchronous rectification for negativ rail ?

Noel Neu

Part Number: UCC24612

Hi,

I would like to use the UCC24612 in a SMPS that has complimentary rail output.

I was wondering if there is any application note on how and if this device can be used for a negative rail.

Thanks !

Hi, Noel:

We have no specific application note to show how to connect UCC24612 in negative output.

We have the application note as below to introduce kinds of the connection of UCC24612. It may help you for your design I think.

Thanks

Regards,

Wesley

Hi Wesley,

Thanks for your reply!

I read through the application note and I see no mention of a negative rail.

Yes, the app note goes through how to use the UCC24612 on the low side, but only to create a positive rail.

Hi, Noel:

May I know what topology you are used?

How do you generate negative rail?

Thanks.
