CM6802BH - PFC/PWM COMBO CONTROLLER

Download the CM6802BH datasheet PDF. This datasheet also covers the CM6802A variant, as both devices belong to the same pfc/pwm combo controller family and are provided as variant models within a single manufacturer datasheet.

Description

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.

Features

  • ‹ Patents Pending ‹ Pin to pin compatible with CM6800,CM6800A, ML4800 and FAN4800. ‹ 23V Bi-CMOS process. ‹ Designed for EPA/80++ efficiency. ‹ CM6802A/B : Selectable Boost output from 380V to 300V during light load. ‹ CM6802AH/BH: Selectable Boost output from 380V to 342V during light load. ‹ All high voltage resistors can be greater than 4.7 Mega ohm (4.7 Mega to 8 Mega ohm) to improve the no load consumption. ‹ Rail to rail CMOS Drivers with on, 60 ohm and off, 30 ohm for both PFC and PWM wit.

CM6802A/B/AH/BH (Dynamic Soft PFC/Green PWM) http://www.championmicro.com.tw EPA/80++ ZVS-Like PFC/PWM COMBO 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 transformer size can be smaller. 6.) To design 12V, 5V and 3.3V output filters can be easy. 7.
