Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 GND GND Power ground and IC ground
2 VOUT O Output Supply pin. Connected to the load
3 FB I Feedback for regulation.
4 EN I Positive polarity. Low = IC shutdown.
5 L I Inductor connection to FETs
6 VIN I Supply from battery
— PAD — For good thermal performance, this pad must be soldered to the land pattern on the PCB
