DESCRIPTION

NAME

NO.

EN

I

Enable pin. Pull High to enable the device. Pull Low to disable the device. This pin has an

internal pull-down resistor of typically 400kΩ when the device is disabled.

VIN

2

PWR

Input pin.

GND

3

Ground pin.

VOUT

4,5

PWR

Output pin.

FB

6

I

Feedback reference pin. An external resistor divider connected to this pin programs the output

voltage.

PG

7

O

Power good open drain output pin. A pull-up resistor can be connected to any voltage less than

6V. Leave it open if it is not used.

SS/TR

8

I

Soft startup and voltage tracking pin. An external capacitor connected to this pin sets the internal

reference voltage rising time.

Exposed Thermal Pad

The exposed thermal pad must be connected to the GND pin. Must be soldered to achieve

appropriate power dissipation and mechanical reliability.
