Flyback converter mosfet selection
Webefficiency is high at heavy load, more than 90% is achievable: TM operation ensures low turn-on losses in the MOSFET and the high PF reduces dissipation in the rectifier bridge. This, in turn, mini- mises requirements on heatsinks; low parts count, which helps reduce encumbrance and assembly cost.
