Functional Pin Description

Pin No.

Pin Name

Pin Function

1

BOOT

Bootstrap capacitor connection node for High-Side Gate Driver. Connect a

0.1

F ceramic capacitor from BOOT to SW to power the internal gate driver.

2

VIN

Supply voltage input, 5.2V to 60V. Bypass VIN to GND with a large

high-quality capacitor.

3

SW

Switch node for output inductor connection.

4, 9

(Exposed Pad)

GND

Power ground. The exposed pad must be connected to GND and well

soldered to the input and output capacitors and a large PCB copper area for

maximum power dissipation.

5

FB

Feedback voltage input. Connect FB to the midpoint of the external

feedback resistor divider to sense the output voltage. The device regulates

the FB voltage at 0.8V (typical) Feedback Reference Voltage.

6

COMP

Compensation node for the compensation of the regulation control loop.

Connect a series RC network from COMP to GND. In some cases, another

capacitor from COMP to GND may be required.

7

EN

current to 3

A or below. Connect EN pin to VIN pin with a 100k pull-up

resistor for automatic startup.

8

SS

Soft-start capacitor connection node. Connect an external capacitor from SS

to GND to set the soft-start time. Do not leave SS pin unconnected. A

capacitor of capacitance from 10nF to 100nF is recommended, which can

set the soft-start time from 1.33ms to 13.3ms, accordingly.
