Pin Functions

PIN DESCRIPTION
NAME NUMBER
dV/dT 1 Connect a capacitor from this pin to GND to control the ramp rate of OUT voltage at device turn-on.
EN/UVLO 2 This is a dual function control pin. When used as an ENABLE pin and pulled down, it shuts off the internal pass MOSFET. When pulled high, it enables the device.
As an UVLO pin, it can be used to program different UVLO trip point via external resistor divider.
GND Thermal Pad GND
ILIM 10 A resistor from this pin to GND will set the overload and short circuit limit.
NC 9 Not Connected Internally. Can be left floating or grounded.
OUT 6-8 Output of the device
VIN 3-5 Input supply voltage
