PIN DESCRIPTION

NAME

FUNCTION

Power Input Pin. Decouple high frequency noise by connecting at least a 0.1μF ceramic capacitor to ground.

GND

Ground.

Enable Input or Alert Output (OTP, OCP, SCP). Asserting EN/nFAULT pin high enables the device. When any of

over-temperature protection, over-current protection, or short-circuit protection occurs, the device sinks current

from EN/nFAULT, pulling the pin down to alert the host (pin as output port).

Soft-Start Pin. The capacitor between SS and GND pins will set the slew rate according to the application

requirements.

EN/nFAULT

Current Limit Program Pin. A resistor between ILIM and GND will set the overload and short-circuit current limit

levels. Do not float this pin.

ILIM

OUT

Power Output Pin.
