Pin No. Mnemonic Description

1

COMP

Compensation Input. Connect a series resistor-capacitor network from COMP to GND to compensate the regulator.

2

FB

Output Voltage Feedback Input. Connect a resistive voltage divider from the output voltage to FB to set the

regulator output voltage.

3

EN

Enable Input. Drive EN low to shut down the regulator; drive EN high to turn on the regulator.

4, 5

GND

Ground.

6, 7

SW

Switching Output. Connect the power inductor from the input voltage to SW and connect the external rectifier

from SW to the output voltage to complete the step-up converter.

8

VIN

Main Power Supply Input. VIN powers the ADP1614 internal circuitry. Connect VIN to the input source voltage.

Bypass VIN to GND with a 10 µF or greater capacitor as close to the ADP1614 as possible.

9

CLRES

Connect a resistor to GND to set the peak inductor current.

10

SS

Soft Start. A capacitor connected from SS to GND brings up the output slowly at power-up and reduces inrush

current.

11

EP

Exposed Die Attach Pad. The exposed pad is not electrically connected; connect this pad to a ground plane for

better heat distribution.
