I/O DESCRIPTION
NAME NO.
Boost voltage that drives the internal NMOS control switch. A bootstrap capacitor is
BOOST 1 I
connected between the BOOST and SW pins.
Signal and Power ground pin. Place the bottom resistor of the feedback network as close as
GND 2 GND
possible to this pin for accurate regulation.
FB 3 I Feedback pin. Connect FB to the external resistor divider to set output voltage.
Enable control input. Logic high enables operation. Do not allow this pin to float or be greater
EN 4 I
than V
IN
+ 0.3 V.
V
IN
5 I Input supply voltage. Connect a bypass capacitor to this pin.
SW 6 O Output switch. Connects to the inductor, catch diode, and bootstrap capacitor.
