    CM6800GIP Electronic IC Chips LOW START-UP CURRENT PFC/PWM CONTROLLER COMBO


    CM6800

    LOW START-UP CURRENT PFC/PWM CONTROLLER COMBO


    GENERAL DESCRIPTION

    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.


    An over-voltage comparator shuts down the PFC section in the event of a sudden decrease in load. The PFC section also includes peak current limiting and input voltage brownout protection. The PWM section can be operated in current or voltage mode, at up to 250kHz, and includes an accurate 50% duty cycle limit to prevent transformer saturation.


    CM6800 includes an additional folded-back current limit for PWM section to provide short circuit protection function.
