PIN DESCRIPTIONS
Pin Name Function
1 BOOST Boost voltage that drives the internal NMOS control switch. A bootstrap capacitor is connected between the
BOOST and SW pins.
2 GND Signal and Power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin
for accurate regulation.
3 FB Feedback pin. Connect FB to the external resistor divider to set output voltage.
4 EN Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than V
IN
+ 0.3V.
5 V
IN
Input supply voltage. Connect a bypass capacitor to this pin.
6 SW Output switch. Connects to the inductor, catch diode, and bootstrap capacitor.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
