说明
- PMP5124, Active Clamp forward (12V@7A). PMP6711 reference design provides an isolated 5.5V at 250mA from a 120VAC/60Hz input in less than 1 square inch of board space. This design uses the TPS40210 in an isolated SEPIC topology with primary side regulation, eliminating the extra space and cost associated with an Optocoupler feedback. The SEPIC clamping capacitor reduces ringing on the drain of the MOSFET and recaptures leakage energy to improve efficiency
