FB
Feedback for Setting the Output Voltage. Connect FB to the center of a resistor
voltage-divider from the output to GND to set positive output voltages.
Output. The output voltage is preset to 15V. Connect a 1μF ceramic capacitor

OUT
from OUT to GND. In shutdown, OUT is pulled to GND by an internal 7.5M ?
resistor.

Ground
Shutdown Input. A logic-low at SHDN places the part in low-power shutdown
mode. Pull SHDN high or connect to V CC for normal operation.
Inductor Switching Connection
Isolation Switch Output. Internally connected to the drain of a p-channel

SW
MOSFET used to isolate the output from the input during shutdown. Connect a
4.7μF ceramic capacitor from SW to GND. If True Shutdown is not required, SW
can be left open with the input supply connected directly to the inductor.

V CC
Input Voltage Supply. Connect a 2.7V to 5.5V input supply to V CC . Connect a
1μF ceramic capacitor from V CC to GND.
