CM6802SAH

CM6802SAH/SBH (Turbo-Speed PFC+Green PWM) http://www.championmicro.com.tw EPA/85+ ZVS-Like PFC+PWM COMBO CONTROLLER Design for High Efficient Power Supply at both Full Load and Light Load GENERAL DESCRIPTION CM6802SAH/SBH is a turbo-speed PFC and a Green PWM controller. It is designed to further increase power supply efficiency while using the relatively lower 380V Bulk Capacitor value. Switching to CM6802SAH/SBH 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.) Turbo Speed PFC may reduce 420 Bulk Capacitor size 4.) 420V bulk capacitor value may be reduced and PFC Boost Capacitor ripple current can be reduced 5.) No Load Consumption can be reduced 290mW at 270VAC 6.) Better Power Factor and Better THD 7.) Clean Digital PFC Brown Out 8.) PWM transformer size can be smaller 9.) Superior Surge Noise Immunity 10.) To design 12V, 5V, and 3.3V output filters can be easy 11.) The stress over the entire external power device is reduced and EMI noise maybe reduced; PFC inductor core might be reduced 12.) Monotonic Output design is easy 13.) And more… Of course, the cost can be reduced CM6802SAH/SBH is pin to pin compatible with CM6800 family. Beside all the goodies in the CM6800, it is designed to meet the EPA/85+ regulation. With the proper design, its efficiency of power supply can easily...
