1 CT Capacitor Setting Shut Down Delay Time
2 OV Over Output Voltage Protection Pin
3 UVLO Two resistors connected from this pin to GND and the power supply respectively is used to
set start-up and shutdown level.
4 EN Enable Pin
5 VIN Input supply pin. This pin must be locally bypassed. 6 VCC This pin should be bypassed to GND with a ceramic capacitor.
7 OUT Connect this pin to the gate of external MOSFET, the gate driver has 1A peak current
capability.
8 GND Ground
9 FAULT
This pin can be used to drive the external MOSFET. The logic of the driver signal is controlled by that of PWM pin and the signal phase of them is the same. This pin is pulled to ground under fault condition of OVP, UVLO, OTP, diode short circuit and LED short circuit. 10 RT An external resistor connected from this pin to GND is used to set the operating frequency. 11 CS Sense switch current pin, which is used for current mode control and for current limit. The current limit voltage is 500mV. 12 SC Slope compensation for current sense. A resistor between SC and GND will program the slope compensation.
13 SS/COMP
An external soft -start time capacitor is placed from this pin to GND and is charged by an internal 20μA current source to control regulator soft-start time. Compensation pin. This pin is the output of the internal error amplifier. 14 FB Voltage feedback pin. The reference voltage is 500mV.
15 PWM This pin can be connected to current matched chip and receives error signal used to shut
down the system. 16 FLAG Fault condition output pin. When the output is in short circuit condition, the FLAG outputs logic low to shut down the power path. Please refer to the application circuit.
