Active Clamp Forward, Flyback for Base Station 3.3V@20A and 15V@1.5A

PMP2844 uses two UCC2897s to generate two isolated outputs from 36V – 72V. The 3.3V at 20A converter uses an active clamp forward topology with synchronous rectifiers. The 15V at 1.5A converter uses a flyback topology. Both converters are operating at 200KHz to keep the efficiency high.
