SWITCHED MODE POWER SUPPLY FOR PLASMA DISPLAY AND ITS STARTING CIRCUIT

摘要

Disclosed are a switched mode power supply for plasma display (PDP) and its starting circuit, the said starting circuit includes: a transistor Q1, a biasing resistance R1, a Zener diode D3 and the second diode D2, the collector of Q1 is electrically connected to the high-voltage input Vin of the switched mode power supply of the PDP, the base of Q1 is electrically connected to the cathode of D3, the emitter of Q1 is electrically connected to the anode of D2, R1 is bridging between the collector and the base of Q1, the anode of D3 is connected to the ground, and the cathode of D2 is electrically connected to the power input Vcc of the control IC.
