CM6807 10-PIN Green-Mode PFC/PWM Combo CONTROLLER for High Density AC Adapter GENERAL DESCRIPTION FEATURES The CM6807 is the Green-Mode PFC/PWM Combo ‹ 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 compliant 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, 67.5kHz. A PFC OVP comparator shuts down ‹ the PFC section in the event of a sudden decrease in load. The PFC section also includes peak current lim.
