Pin Definitions
Pin # Name Description
1
RANGE
RANGE pins impedance changes according to VIN pin voltage level. When the input voltage
etected by the VIN pin is lower than a threshold voltage, it sets to high impedance; whereas it
ets to low impedance if input voltage is 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 the PFC voltage feedback loop allows a simple compensation circuit between
his 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.
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 (0.6 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 on time.
