CM6502THH (Turbo-Speed PFC)
http://www.championmicro.com.tw
EPA/90+ ZVS-Like PFC CONTROLLER
Design for High Efficient Power Supply at both Full Load and Light Load
GENERAL DESCRIPTION
CM6502THH is a ZVS-Like Single PFC and it is designed
to meet 90+ spec. (total efficiency). It has the following key
features.
1.) Around 2% efficiency gain when the output load is
below 40% of the full load
2.) 420V bulk capacitor value 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 next
stage controller or the House Keeping IC at
secondary side. It has a customer programmable
low threshold PGTHL
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 determine is low
line; therefore at light load, Bulk capacitor 380V can
drop to 355V
7.) No Load Consumption can be reduced to 290mW at
270VAC
8.) Better Power Factor and Better THD
9.) Clean Digital PFC Brown Out
10.) The stress over the entire external power device is
reduced and EMI noise reduced
11.) Superior Surge Noise Immunity
CM6502THH is designed to meet the EPA/90+ regulation.
With the proper design, its efficiency of power supply can
easily approach 90+.
FEATURES
‹ Patents Pending
‹ 23V Bi-CMOS process.
‹ Designed for EPA/90+efficiency
‹ Selectable Boost output from 380V to 355V during light
load
‹ Customer Programmable the Low Threshold of PGB
comparator at PGTHL pin
‹ “Remember It was Light Load” function to improve the
efficiency
‹ “Remember It was Full Load” function to improve the
efficiency
‹ Initially, Vin at 230Vac , IC internal determine is low line;
therefore at light load, Bulk capacitor 380V can drop to
355V
‹ Clean Digital PFC Brown Out
‹ All high voltage resistors can be greater than 5 Mega
ohm (5 Mega to 8 Mega ohm) to improve the no load
consumption.
‹ Rail to rail CMOS Drivers with on, 60 ohm and off, 30
ohm with 17V zeners.
‹ Fast Start-UP Circuit without extra bleed resistor to aid
VCC reaches 13V sooner.
‹ Low start-up current (50uA typ.)
‹ Low operating current (2.1mA typ.)
‹ Adjustable Long Delay Time for Line Sagging
(Up to 2 Second)
‹ 16.5V VCC shunt regulator
‹ Dynamic Soft PFC to ease the stress of the Power
Device and Ease the EMI-filter design.
‹ Better Power Factor and Better THD
‹ Average current, continuous or discontinuous boost
leading edge PFC.
‹ Current fed Gain Modulator for improved noise immunity.
‹ Gain Modulator is a constant maximum power limiter.
‹ Precision Current Limit, over-voltage protection, UVLO,
and soft start, and Reference OK.

PGB is the PG comparator output. The input of PG
comparator is using Vfb (pin 13) to compare with the high

PGTHL (pin 6, Set by user).
When 380V is ready, pin 9 is open-drain and it will be
pulled low.
