Description

The PMP5353 reference design provides a non-isolated 3.3V at 40mA and 15V at 2mA from a 120VAC/60Hz input in less than 1 square inch of board space. This design uses the UCC38C44 to control a SEPIC topology. The SEPIC clamping capacitor reduces ringing on the drain of the MOSFET and recaptures leakage energy to improve efficiency. A TPS72901 LDO is used to minimize noise on the 3.3V output.
