CM6800 and CM6801 are the single chip PFC+PWM control integrated circuit produced by CMC Corp., the USA, which is widely used in PC power supply, air-conditioner, large screen color TV, monitor, UPS and AC adapter, etc.1.function featuresCM6800 and CM6801 have functions of over-voltage protection, over-current protection and over-heat protection, the power factor is close to 1. The PWM in them is added with the current limitation function; 23VBi-coms process has the synchronized leading edge PFC and rear edge PWM, which provides with high switch ratio for rising the reaction speed; the fault amplifier works in a low starting circuit and low working current.
