GND
Function
Output switch. Connect to the inductor and catch diode.
Signal and power ground pin. Place the bottom resistor of the feedback network as close as
possible to this pin.
Feedback pin. Connect to 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 VIN + 0.3V.
Input supply voltage.

Function
Feedback pin. Connect to external resistor divider to set output voltage.
Signal and power ground pin. Place the bottom resistor of the feedback network as
close as possible to this pin.
Output switch. Connect to the inductor and catch diode.
Power Input supply.
Control circuitry supply voltage. Connect VINA to VIND on PC board.
Enable control input. Logic high enables operation. Do not allow this pin to float or be
greater than VINA + 0.3V.
Connect to system ground for low thermal impedance, but it cannot be used as a
primary GND connection.
