PMP2844, Active Clamp forward, Flyback for Base Station 3.3V@20A and 15V@1.5A

PMP2844, 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
