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