CM6802A/B/AH/BH (Dynamic Soft PFC/Green PWM) http://.championmicro..tw EPA/80++ ZVS-Like PFC/PWM BO CONTROLLER
Design for High Efficient Power Supply at both Full Load and Light Load
GENERAL DESCRIPTION
Switching to CM6802A/B/AH/BH from your existing CM6800 family boards can gain the following advanced performances:
1.) Around 2% efficiency gain when the output load is below 40% of the full load.
2.) Hold Up time can be increased ~ 30% from the existing 6800 power supply.
3.) 420V bulk capacitor value may be reduced PFC boost ripple current can be reduced; therefore, the boost inductor core size maybe reduced.
4.) No Load Consumption can be reduced 290mW at 270VAC.
5.) PWM...
