19 to 30Vin 12V@10A Active Clamp Forward Reference Design


Design files


This reference design provides an isolated 12V at 10A from a 19V-30V input with greater than 93% efficiency. This design uses the UCC2897A active clamp controller with CSD18532Q5B synchronous rectifiers for an efficient, yet cost effective solution that can operate from a 24VDC input bus.
