PIN FUNCTIONS

SOIC-8

EP

Pin #

Name

Description

1

PG

Power Good. Requires an external pull-up resistor because it is an open drain. When VOUT

reaches 80% of its normal output voltage, PG goes high after a 245µs delay.

2

GND

Ground.

3

FB

Output Voltage Feedback. Connect to a capacitor to VOUT to improve low dropout stability.

Internally voltage divider set the output to be 12V. Connect to the tap of a resistor divider to

adjust the output voltage.

4

VOUT

Output Voltage.

5

VD

Connect a cap from this pin to GND to store energy for the low drop-out stage.

6

VB

Connect with VD directly.

7

NC

Not Connected.

8

VIN

Voltage Input Supply. Providing energy when the voltage falls within the charging window.

Expose

pad

Connect to a large copper surface connected to GND to enhance thermal dissipation.
