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

SD

Shutdown Input. Drive SD low to shut down the regulator; drive SD high to turn it on.

4

GND

Ground.

5

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.

6

IN

Main Power Supply Input. IN powers the ADP1610 internal circuitry. Connect IN to the input source voltage.

Bypass IN to GND with a 10 µF or greater capacitor as close to the ADP1610 as possible.

7

RT

Frequency Setting Input. RT controls the switching frequency. Connect RT to GND to program the oscillator to

700 kHz, or connect RT to IN to program it to 1.2 MHz.

8

SS

Soft Start Timing Capacitor Input. A capacitor from SS to GND brings up the output slowly at power-up.
