Product description:

CM6502UHH (1MHz PFC) EPA/90+ ZVS-Like PFC Controller

CM6502UHH is a ZVS-Like single PFC and it is designed to meet EPA 90+ spec. (total efficiency). It has the following key features.

1.) Around 2% efficiency gain when the output load is below 60% of the full load;

2.) High voltage 420V bulk capacitor can be reduced, and also PFC boost capacitor ripple current can be reduced;

3.) Turbo speed PFC may reduce 420 bulk capacitor size further

4.) A PGB function is designed for interfacing to the next stage controller or the housekeeping IC on the secondary side. The PGB function pulls low was decided by IC inside. The PGB pull high has a customer programmable by PGTHL low threshold;

5.) “Remember it was light load” function and “Remember it was full load” function may reduce PFC 420V bulk capacitor size further. It boosts the total efficiency as well;

6.) Initially, Vin at 230Vac, IC internal AC high line comparator determine is a low line; therefore at light load, bulk capacitor 380V can drop to 355V for CM6502UHH;

7.) IAC, Vrms, VFB pin resistor can be used> 5M ohm. It will help no-load consumption to reduce at 270VAC;

8.) Better power factor and better THD;

9.) Clean digital PFC brownout;

10.) Dynamic soft PFC to ease the stress over the entire external power device is reduced and EMI noise reduced;

11.) Superior surge noise immunity.
