PIN

PIN Name

Description

1

EN

Regulator On/off Control Input. A logic high input(VEN>1.4V) turns on

the regulator. A logic low input(VEN<0.4V) puts the LP6250 into low

current shutdown mode.

2

Out

Voltage output pin.

3

FB

Regulation Feedback Input. Connect to an external resistive voltage

divider from the output to FB to set the output voltage.

4

LBO

Open-drain Low Battery Detector output pin.

5,10

GND

Power Ground.

6

BATT

Battery supply input pin.

7

LBI

Battery detector input pin.

8

NC

No Connector.

9

SW

Output switching node. SW is the drain of the internal N-Channel

MOSFET and RDS-ON is 250m

Ω. Connect the inductor to SW to

Complete the step-up converter.

11

EPGND

Exposed PAD. Must connect to Ground.
