10-PIN Green-Mode PFC/PWM Combo CONTROLLER for High Density AC Adapter

GENERAL DESCRIPTION\nThe CM6805A and CM6806A are the Green-Mode PFC/PWM Combo controller for High Density AC Adapter. For the power supply, its input current shaping PFC performance could be very close to the performance of the CM6800 or ML4800 leading edge modulation average current topology.\nCM68 ♦ Both PFC and PWM have the Green Mode to meet blue angel and energy star spec.\n♦ 10-Pin SOIC package\n♦ PWM pulse skipping for the green mode\n♦ Use RAC as the Startup resistor around 5 Mega Ohm at IAC pin\n♦ It can use the HV bipolar to start up the chip and it helps green mode.\n♦ Easy to config;
