10-PIN Green-Mode PFC/PWM bo CONTROLLER for High Density AC Adapter
GENERAL DESCRIPTION
Features
The CM6805A and CM6806A series are monolithic ICs without software embedded, the Green-Mode PFC/PWM bo controller for High Density AC Adapter. For the power supply less than 200Watt, its input current shaping PFC performance could be very close to the performance of the CM6800 or ML4800 leading edge modulation average current topology.
CM6805A/CM6806A 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 CM6805A / CM6806A includes circuits for the implementation of a leading edge, input current shaping technique “boost” type PFC and a trailing edge, PWM.
The CM6805A’s PFC and PWM operate at the same frequency, 67.5k Hz. A PFC OVP parator shuts down the PFC section...
