Functional Pin Description

Pin No.

Pin Name

Pin Function

Bootstrap Supply for High-Side Gate Driver. Connect a 1F ceramic

capacitor between the BOOT and SW pins.

BOOT

GND

Power Ground.

Soft-Start Time Setting. Connect a capacitor from SS to GND to set the

soft-start period.

Feedback Voltage Input. The pin is used to set the output voltage of the

converter via a resistive divider. The converter regulates V_FBto 0.6V.

PGOOD

Power Good Indicator Output.

Enable Control Input. Connect EN to a logic-high voltage to enable the IC or

to a logic-low voltage to disable. Do not leave this high impedance input

unconnected.

Power Input. The input voltage range is from 4.3V to 18V. Must bypass with

a suitable large ceramic capacitor at this pin.

VIN

Switch Node. Connect to external L-C filter.
