Description

1

Vin

IC Power Supply.

2

GND

Ground.

3

OCP

Current Limit

Adjustable pin.

4

LX

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

MOSFET and RDS-ON is 100m

Ω. Connect the inductor to SW to

Complete the step-up converter.

5

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 LP6217 into low

current shutdown mode.

6

FB

Regulation Feedback Input. Connect to an external resistive voltage

divider from the output to FB to set the output voltage.Vfb=0.6V.
