Pin Definitions

Pin #

Name Description

WLCSP MLP

MODE. Logic 1 on this pin forces the IC to stay in PWM mode. A logic 0 allows the IC to automatically

A1

3 MODE switch to PFM during light loads. The regulator also synchronizes its switching frequency to four times

the frequency provided on this pin. Do not leave this pin floating.

B1

2 SW Switching Node. Connect to output inductor.

C1

1 FB Feedback / VOUT. Connect to output voltage.

C2

6 GND Ground. Power and IC ground. All signals are referenced to this pin.

B2

5

EN

Enable. The device is in shutdown mode when voltage to this pin is <0.4V and enabled when >1.2V.

Do not leave this pin floating.

A2

4 VIN Input Voltage. Connect to input power source.
