CM6802BHGIS Product details

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 bereduced; 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.)  The stress over the entire external power device is reduced and EMI noise maybe reduced.

8.)  Monotonic Output design is easy and more…Of cause, the cost will be reduced.



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 with two 17V zeners.

Fast Start-UP Circuit without extra bleed resistor to aid VCC reaches 13V sooner.

Low start-up current (55uA typ.) 

Low operating current (2.5mA typ.)

16.5V VCC shunt regulator 

Leading Edge Blanking for both PFC and PWM.

fRTCT = 4*fpfc =4*fpwm for CM6802A//AH

fRTCT = 4*fpfc =2*fpwm for CM6802B/BH
