    Sema Atx Smps

    This document contains a circuit diagram for a switching mode power supply (SMPS) that converts 220V AC to -50V, 0V, +12V, and +50V DC voltages. The SMPS uses MOSFETs, diodes, capacitors, resistors, and integrated circuits to step down the voltage and provide isolation between the input and outputs. Control and drive signals are generated by an IR2153 integrated circuit.
