PMP7249, High Line Input to 12V at 1A Primary Side Regulated, Quasi Resonant Flyback Reference Design

PMP7249, High Line Input to 12V at 1A Primary Side Regulated, Quasi Resonant Flyback Reference Design. Low component count and low cost isolated flyback, converting the high line mains (180Vac to 275Vac) to 12V at 1A, 1.2Amax. Thanks to the UCC28700 controller, no optocoupler is needed to close the loop
