Pin Description

Pin Number

Pin Name

Function

A1

FB

Feedback Analog Input. Connect to the output at the output filter capacitor (Figure 1)

B1

VID1

Output Voltage Control Inputs. Set the output voltage using these digital inputs (see Table

1). The output defaults to 1.5V if these pins are unconnected.

C1

VID0

D1

SYNC/MODE

Synchronization Input. Use this digital input for frequency synchronization or modulation

control. Set:

SYNC/MODE = high for low-noise 600kHz PWM mode

SYNC/MODE = low for low-current PFM mode

SYNC/MODE = 500kHz - 1MHz external clock for synchronization to an external clock in

PWM mode. See Synchronization and Operating Modes in the Device Information section.

D2

EN

Enable Input. For shutdown, set low to SGND.(See Shutdown Mode in the Device

Information section.)

D3

PGND

Power Ground
