... SOP package 10. No internal Zener and VCCOVP comparator The CM6805BO operates both PFC and PWM sections at 100kHz. This allows the use of smaller PWM magnetic and output filter components, while minimizing switching losses in the PFC stage. Several protection features have been built into the CM6805BO ...

... AC line in phase with and proportional to the input voltage, a way must be found to prevent that device from loading the line except in proportion to the instantaneous line voltage. The PFC section of the CM6805BO uses a boost-mode DC-DC converter to accomplish this. The input to the converter is the full wave rectified AC line voltage. No ...

... PFC Section: PFC Voltage Loop Error Amp, VEAO The ML4803 utilizes an one pin voltage error amplifier in the PFC section (VEAO). In the CM6805BO using the slew rate enhanced transconductance amplifier, which is the same as error amplifier in the CM6800. The unique transconductance profile can speed up the conventional transient response by 10 times ...

... PFC Tri-Fault detect is an entirely internal circuit. It requires no external components to serve its protective function. VCC over voltage and generate VCC For the CM6805BO system, if VCC is generated from a source that is proportional to the PFC output voltage. The PFC OVP will avoid the VCC over voltage. Given that 16V on VCC corresponds to 380V on the PFC output, 17 ...
