CM6502S - EPA/90+ ZVS-Like PFC CONTROLLER

Description

CM6802S is a ZVS-Like Single PFC and it is designed to meet 90+ spec.

( total efficiciency).

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 stress over the entire external power device is reduced and EMI noise reduced. 6.) A PGB function is designed for interfa.
