Pin Name Function
1 FB Feedback pin. Connect to external resistor divider to set output voltage.
2 GND Signal and power ground pin. Place the bottom resistor of the feedback network as close as
possible to this pin.
3 SW Switch Node. Connect to the inductor and catch diode.
4 VIND Power Input supply.
5 VINA Control circuitry supply voltage. Connect VINA to VIND on PC board.
6 EN Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than
VINA + 0.3V.
DAP Die Attach Pad Connect to system ground for low thermal impedance, but it cannot be used as a primary GND
connection.
