Hi Tiers,

The customer want to find active clamp which can realize secondary drive with pre bias function.

Could UCC2897A achieve this function?

If yes, is there reference schematic or reference design?

Thanks and best regards,

Jamie

Hello Jamie,

The UCC2897A can be used with the UCC24610 SR controller.

The SR controller will allow pre bias startup and prevent reverse currents through the transformer.

I am attaching a schematic and test report for this reference design.
