CM6800 - 虹冠電子

CM6800 . LOW START-UP current PFC/PWM CONTROLLER COMBO. GENERAL DESCRIPTION FEATURES. The CM6800 is a controller for power factor corrected, Patent Number #5,565,761, #5,747,977, #5,742,151, switched mode power suppliers. Power Factor Correction #5,804,950, #5,798,635. (PFC) allows the use of smaller, lower cost bulk Pin to pin compatible with ML4800 and FAN4800. capacitors, reduces power line loading and stress on the Additional folded-back current limit for PWM section. switching FETs, and results in a power supply that fully 23V Bi-CMOS process compiles with IEC-1000-3-2 specifications. Intended as a VIN OK turn on PWM at instead of BiCMOS version of the industry-standard ML4824, Internally synchronized leading edge PFC and trailing CM6800 includes circuits for the implementation of leading edge PWM in one IC.
