Functional Pin Description
PIN
PIN Name
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.
