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