The power supply of ! CM6500/01 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-1000-2-3 specifications. CM6500/1 includes circuits for the implementation of leading edge, average current, “boost” type power factor correction and a synchronized 47% PWM clock. The CM6500/1 has additional Features besides all the Features of CM6800. Additional Features are Inrush Current Control, Separated PFC OVP pin, Separated Power VCC pin and Analog VCC pin, and Separated Power Ground pin and Analog Ground pin. 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...
