Pin Functions

PIN TYPE DESCRIPTION
No. NAME
1 dV/dT O Connect a capacitor from this pin to GND to control the ramp rate of OUT voltage at device turnon
2 EN/UVLO I 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
3 VIN I Input supply voltage
4
5
6 OUT O Output of the device
7
8
9 NC NC Not Connected Internally. Can be left floating or grounded
10 ILIM O A resistor from this pin to GND sets the overload and short circuit limit
Thermal Pad GND Ground GND
