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.
Shutdown Input. Drive SD low to shut down the regulator; drive SD high to turn it on.
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.
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.
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 the oscillator to 1.2 MHz.
Soft Start Timing Capacitor Input. A capacitor from SS to GND brings up the output slowly at power-up.
