Beschreibung
The PMP20634 reference design is an isolated DCM flyback design that takes a universal line input 85VAC to 265VAC, and produces a 12V ouput capable of 12W loading. The design uses the UCC28730 controller that achieves ultra-low standby power at no load. It achieves 85% efficiency at high and low line, and measures 1in x 3in on a 2 layer board
