With the fast development of the tablet PC, the increasing load demand requires the adapter tohave high power density, high efficiency, and low profile. This application note presents a highefficiency Flyback converter with output synchronous rectification, which can achieve highefficiency within a wide load range to meet the high density requirements. By using TexasInstrument’s UCC28610 green mode controller and the UCC24610 Synchronous Rectifier (SR)controller, a 17W SR Flyback converter reference design, PMP4305, with 5.6V output voltagedemonstration board is designed with experimental verification.
