Tpv56pb801 Schematic Diagram Pdf Upd < FULL - Breakdown >

: Manages AC mains filtering via an Electro-Magnetic Interference (EMI) circuit containing choke inductors, X-capacitors, and a primary bridge rectifier. It passes raw DC power through a Pulse Width Modulation (PWM) switching controller and a power MOSFET to feed the high-frequency switching transformer.
