CM6800A Datasheet (Champion Microelectronic) - LOW START-UP CURRENT PFC/PWM CONTROLLER COMBO

CM6800A, LOW START-UP CURRENT PFC/PWM CONTROLLER COMBO

switched mode power suppliers.

Power Factor Correction (PFC) allows the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply that fully compiles with IEC-1000-3-2 specifications.

Intended as a BiCMOS version of
