Beschreibung

The PMP10936 reference design uses the UCC28740 to provide an isolated 12V at 2.5A output. The UCC24632 is used to control a synchronous recitifer for high efficiency. The two-switch flyback topology recycles the transformer's leakage energy and provides a further improvement in efficiency.
