Pin Description
Supply voltage input.
Ground.
Enable Input. Logic high enables the chip and logic low disables the chip and reduces
supply current to <1µA. Do not float this pin.
Feedback Input. In case of fixed voltage options, connect this pin directly to the output.
For an adjustable voltage option, connect this pin to the resistor divider.
Inductor pin. This pin is connected to the internal MOSFET switches.
