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.
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.
Main Power Supply Input. VIN powers the ADP1612/ADP1613 internal circuitry. Connect VIN to the input source
voltage. Bypass VIN to GND with a 10 μF or greater capacitor as close to the ADP1612/ADP1613 as possible.
Frequency Setting Input. FREQ controls the switching frequency. Connect FREQ to GND to program the oscillator
to 650 kHz, or connect FREQ to VIN to program it to 1.3 MHz. If FREQ is left floating, the part defaults to 650 kHz.
Soft Start Timing Capacitor Input. A capacitor connected from SS to GND brings up the output slowly at power-
up and reduces inrush current.
