Description
1
RANGE
he RANGE pins impedance changes according to VIN pin voltage level. When the input voltage
etected by the VIN pin is higher than a threshold voltage, it sets to low impedance; whereas it
ets to high impedance if input voltage is at a high level.
2
COMP
utput pin of the error amplifier. It is a transconductance-type error amplifier for PFC output
oltage feedback. Proprietary multi-vector current is built-in to this amplifier; therefore, the
ompensation for PFC voltage feedback loop allows a simple compensation circuit between this
pin and GND.
3
INV
Inverting input of the error amplifier. This pin is used to receive PFC voltage level by a voltage
ivider and provides PFC output over- and under-voltage protections. This pin also controls the
PWM startup. Once the FAN6920MR is turned on and V
INV
exceeds in 2.3 V, PWM starts.
4
CSPFC
Input to the PFC over-current protection comparator that provides cycle-by-cycle current limiting
protection. When the sensed voltage across the PFC current-sensing resistor reaches the internal
hreshold (0.82 V typical), the PFC switch is turned off to activate cycle-by-cycle current limiting.
5
CSPWM
Input to the comparator of the PWM over-current protection and performs PWM current-mode
ontrol with FB pin voltage. A resistor is used to sense the switching current of the PWM switch
nd the sensing voltage is applied to the CSPWM pin for the cycle-by-cycle current limit, current-
mode control, and high / low line over-power compensation according to DET pin source current
uring PWM t
