6-Lead TSOT
Boost voltage that drives the internal NMOS control switch. A
bootstrap capacitor is connected between the BOOST and SW
pins.
Signal and Power ground pin. Place the bottom resistor of the
feedback network as close as possible to this pin for accurate
regulation.
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 than V
Input supply voltage. Connect a bypass capacitor to this pin.
Output switch. Connects to the inductor, catch diode, and
bootstrap capacitor.
