Overview
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...
