NOTES

1. THE EXPOSED PAD IS NOT ELECTRICALLY

CONNECTED; CONNECT THIS PAD TO A GROUND

PLANE FOR BETTER HEAT DISTRIBUTION.

COMP

Description

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

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

regulator output voltage.

4, 5

6, 7

GND

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

Ground.

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.

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.

CLRES

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

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

current.

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

better heat distribution.
