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
Bypass VIN to GND with a 10 µF or greater capacitor as close to the
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.
NOTES
1. THE EXPOSED PAD IS NOT ELECTRICALLY
CONNECTED; CONNECT THIS PAD TO A GROUND
