Description

WLCSP

MLP

A1, B1

9

PGND

Power GND. Power return for gate drive and power transistors. Connect to AGND on PCB. The

connection from this pin to the bottom of CIN should be as short as possible.

A2

10

SW

Switching Node. Connect to output inductor.

A3

1

PVIN

Power Input Voltage. Connect to input power source. The connection from this pin to CIN should be as

short as possible.

B2

N/A

SYNC

Sync. When toggling and SYNC_EN bit is HIGH, the regulator synchronizes to the frequency on this pin.

In PWM mode, when this pin is statically LOW or statically HIGH, or when its frequency is outside of the

specified capture range, the regulator’s frequency is controlled by its internal 3MHz clock.

B3

2

AVIN

Analog Input Voltage. Connect to input power source as close as possible to the input bypass

capacitor.

C1

8, PAD

AGND

Analog GND. This is the signal ground reference for the IC. All voltage levels are measured with respect

to this pin.

C2

7

EN

Enable. When this pin is HIGH, the circuit is enabled. When LOW, quiescent current is minimized. This

pin should not be left floating.

C3

3

SDA

SDA. I

2C interface serial data.

D1

6

VOUT

Output Voltage Monitor. Tie this pin to the output voltage. This is a signal input pin to the control circuit

and does not carry DC current.

D2

5

VSEL

Voltage Select. When HIGH, VOUT is set by VSEL1. When LOW, VOUT is set by VSEL0. This behavior

can be overridden through I

2C register settings. This pin should not be left floating.

D3

4

SCL

SCL. I

2C interface serial clock.

Note:

5.

All logic inputs (SDA, SCL, SYNC, EN, and VSEL) are high impedance and should not be left floating. For minimum

quiescent power consumption, tie unused logic inputs to AVIN or AGND. If I

2C control is unused, tie SDA and SCL to AVIN.
