The absolutely available switch power supply: Panasonic M12H power supply

Published:2011/6/10 1:05:00 Author:Seven | Keyword: switch power supply, Panasonic | From:SeekIC

The power supply is used in Panasonic color TV of TC-230H、TC-2030DHN、TC-830D、TC-840D, etc. Oscillating processThe DC voltage on C836 runs across P1 and P2 coils of T801, and the reaches C pole of the internal switch of IC801 1-pin, in the mean time, it is imposed on B pole of the internal switch of IC801 2-pin by R803, the switch pipe starts to conduct, and the current of E pole runs out from 4-pin of IC801. The current in P1 and P2 coil of T801 is rising and generates sensing signals, the signals are coupled with F2 and F3, at the moment, the sensing voltage polarity of F2 is positive, while F3 is negative.
