Pin Functions

PIN I/O DESCRIPTION
NAME NO.
SS 1 O Soft-start terminal. Connecting an external capacitor slows down the output voltage ramp rate after enable event. The soft-start terminal can be used to disable the device as described in theSoft Start section.
EN 2 I Enable terminal. Driving this terminal to logic high enables the device; driving the terminal to logic low disables the device. VIN voltage must be greater than 3.5 V when using the EN pin. For VIN < 3.5 V, enable terminal cannot be used to disable the device.
TI recommends to connect the enable terminal to VIN.
VIN 3 I Unregulated supply voltage. TI recommends to connect an input capacitor as a good analog circuit practice.

PCL 7 O Programmable current limit. A resistor to GND sets the overcurrent limit activation point.
The range of resistor that can be used on the PCL terminal to GND is 8.2 kΩ to 160 kΩ.
GND 8 — Ground/thermal pad.(1)
PG/OC 9 O Power Good terminal. PG is an open-drain output to indicate the output voltage reaches 90% of target. PG terminal is also used as indicator when an overcurrent condition is activated. PG pin should have a pull-up resistor to the VOUT pin.
CS 10 O Current sense terminal. Resistor connected from CS to VIN. CS terminal indicates voltage proportional to output current.
CS terminal low: Foldback current limit disabled
CS terminal high: Foldback current limit enabled
VOUT 11 O Regulated output.

COMP 15 I Internal compensation point for error amplifier.
FB 16 I The output voltage feedback input through voltage dividers. See Adjustable Output Voltage (Feedback Circuit) section.
(1) Thermal pad must be connected to GND.
