Quasi Resonant Flyback, 80-440V AC, 12V@0.5A using UCC28600 up to 91% efficiency PMP7019 (ACTIVE)
See the Important Notice and Disclaimer covering reference designs and other TI resources.
The PMP7019 reference design is a wide-input Quasi Resonant Flyback designed for industrial applications. It uses the UCC28600 controller to an isolated 48V/1A output from an 80Vac to 440Vac input range. The quasi-resonant switching of the UCC28600 allows this design to achieve a maximum load efficiency up to 91%.
