PIN DESCRIPTION
The SW pin is the switching node of the power converter. Connect one terminal of
the inductor to the SW pin and the other to power input.

GND
EN
System ground
The EN pin is an active-high logic input for enabling the device. When asserted high,
the boost function begins. When asserted low, the device is completely disabled,
and current is blocked from flowing from the SW pin to the output and vice versa.
This pin should be tied either high to enable the device or low to disable.

FAULT
Fault output; outputs logic LOW under a number of fault conditions (see Table 1 on
page 10).

FB
Feedback pin of the converter. Connect voltage divider resistors between VOUT, FB
and GND for desired output. See Figures 3A, 4A, and 5A.
