CM6801
CM6801 is LOW START-UP CURRENT PFC/PWM CONTROLLER COMBO manufactured by Champion.
DESCRIPTION
FEATURES
The CM6800/1 is a monolithic IC without software embedded, 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 piles with IEC-1000-3-2 specifications. Intended as a Bi CMOS version of the industry-standard ML4824, CM6800/1 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 ponent costs.
An over-voltage parator shuts down the PFC section in the event of a sudden decrease in load. The PFC section also includes peak current...
