آیسی کنترلاصلاح ضریب توان و pwm LOW START-UP CURRENT PFC/PWM CONTROLLER COMBO

 

The CM6800 is a controller for power factor corrected,
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 the industry-standard ML4824,
CM6800 includes circuits for the implementation of leading
edge, average current, “boost” type power factor
correction and a trailing edge, pulse width modulator
(PWM). Gate-driver with 1A capabilities minimizes the
need for external driver circuits. Low power requirements
improve efficiency and reduce component costs.
