EPA/90+ ZVS-Like PFC CONTROLLER
Design for High Efficient Power Supply at both Full Load and Light Load
GENERAL DESCRIPTION
CM6802S is a ZVS-Like Single PFC and it is designed to meet 90+ spec. ( total efficiciency). It has the following key Features
.
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 can be reduced, and also PFC boost ripple current can be reduced; therefore, the boost inductor core size may be reduced.
4.) No Load Consumption can be reduced to 290mW at 270VAC.
5.) The...
