CM6807
CM6807 is 10-PIN Green-Mode PFC/PWM Combo CONTROLLER manufactured by Champion Microelectronic.
10-PIN Green-Mode PFC/PWM bo CONTROLLER for High Density AC Adapter
GENERAL DESCRIPTION
Features
The CM6807 is the Green-Mode PFC/PWM bo controller for High Density AC Adapter. For the power supply less than 200Watt, it’s input current shaping PFC performance could be very close to the performance of the
CM6800 or ML4800 leading edge modulation average current topology.
CM6807 offers the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply fully pliant to IEC1000-3-2 specifications. The CM6807 includes circuits for the implementation of a leading edge, input current shaping technique “boost” type PFC and a trailing edge, PWM.
The CM6807’s PFC and PWM operate at the same frequency, 67.5k Hz. A PFC OVP parator shuts down the PFC section in the event of a sudden decrease in load.
The PFC section also includes peak current...
