Pin Descriptions

Pin

Number

Pin

Name

Function

1

PVIN

Supply Voltage to power FETs. PVIN is connected to VIN internally.

2, 11

SW

Switch Output. Pin 2 and 11 can be connected together.

3, 12

PGND

Power Ground. Pin 3 and 12 can be connected together.

4

AGND

Quiet ground for controller circuits

5

NC

Leave this pin open. Do not connect it to ground.

6

OUT

Input sense pin for output voltage

7

FB

Feedback. An external resistor divider from the output to GND, tapped to the FB pin, sets the output voltage.

8

EN

On/Off Control.

9

PG

Power Good Indicator. The output of this pin is an open drain with internal pull up resistor to VIN. PG is pulled

up to VIN when the FB voltage is within 10% of the regulation level, otherwise it is LOW.

10

VIN

Supply Voltage to internal control circuitry. VIN is connected to PVIN internally.
