Pin Functions (continued)
PIN
I/O DESCRIPTION
NAME NO.
Output Voltage Sense: An external resistor-divider network connected from this pin to the PFC output
voltage provides feedback sensing for regulation to the internal 5-V reference voltage. A small capacitor from
this pin to GND filters high-frequency noise. Standby disables the controller and discharges VCOMP when
the voltage at VSENSE drops below the Open-Loop Protection (OLP) threshold of 16.5%V
REF
(0.82 V). An
internal 100-nA current source pulls VSENSE to GND during pin disconnection. Enhanced Dynamic
VSENSE 6 I
Response (EDR) rapidly returns the output voltage to its normal regulation level when a system line or load
step causes VSENSE to rise above 105% or fall below 95% of the reference voltage. Two level Output Over-
Voltage Protection (OVP): a 4-k resistor connects VCOMP to ground to rapidly discharge VCOMP when
VSENSE exceeds 107% (V
OVP_L
) of the reference voltage. If VSENSE exceeds 109% (V
OVP_H
) of the
reference voltage, GATE output will be disabled until VSENSE drops below 102% of the reference voltage.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other condition beyond those included under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods of time may affect device reliability.
