CM6807AGR中文资料10-PIN Green-Mode PFC/PWM Combo CONTROLLER for High Density AC Adapter数据手册Champion规格书

描述 Description

GENERAL DESCRIPTION
The CM6807A is the Green-Mode PFC/PWM Combo controller for High Density AC Adapter. For the power supply less than 200Watt, it’sinput current shaping PFC performance could be very close to the performance of the CM6800 or ML4800 leading edge modulation average current topology.FEATURES
Patent Filed #5,565,761,#5,747,977, #5,742,151, #5,804,950, #5,798,635
Both PFC and PWM have the Green Mode to meet blue angel and energy star spec.
10-Pin SOIC package
PWM pulse skipping for the green mode
Use RAC as the Startup resistor which can be 2000K or higher at IAC pin
It can use the HV bipolar to start up the chip and it helps green mode.
Easy to configure into Boost Follower
Enable lowest BOM for power supply with PFC
Internally synchronized PFC and PWM in one IC
Patented slew rate enhanced voltage error amplifier with advanced input current shaping technique
Universal Line Input Voltage
CCM boost or DCM boost with leading edge modulation PFC using Input Current Shaping Technique
Feedforward IAC pin to do the automatic slope compensation
PFCOVP, VCCOVP, Precision -1V PFC ILIMIT, PFC Tri-Fault Detect comparator to meet UL1950
Low supply currents; start-up: 100uA typical, operating current: 2mA typical.
Synchronized leading PFC and trailing edge modulation PWM to reduce ripple current in the storage capacitor
between the PFC and PWM sections and to reduce switching noise in the system
VINOK Comparator to guarantee to enable PWM when PFC reach steady state 
High efficiency trailing-edge current mode PWM
Exact 50% PWM maximum duty cycle
UVLO, REFOK, and brownout protection
Digital PFC and PWM soft start, ~10mS
Precision PWM 1.5V current limit for current mode operation
PWMtrifault to sense DC to DC short and Turn off PFC at GMth
PWMtrifault also can be programmed to do the Thermal ProtectionAPPLICATIONS
