CM6803(A;B;C)
10-PIN Green-Mode PFC/PWM Combo CONTROLLER for LCD Standby Power
GENERAL DESCRIPTION
FEATURES
The CM6803A is the Green-Mode PFC/PWM Combo
controller for Standby in LCD power. For the LCD power
supply, its input current shaping PFC performance could be
very close to the performance of the CM6800 or ML4800
leading edge modulation average current topology.
CM6803A 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 CM6803A /
CM6808A includes circuits for the implementation of a
leading edge, input current shaping technique “boost” type
PFC and a trailing edge, PWM.
The CM6803A’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 limiting...
