Description
Supply Voltage Input.
Ground.
Enable Input. Logic HIGH enables the chip; logic LOW disables the chip and reduces supply
current to <1µA. Do not float this pin. If the EN pin is tied to V
than 5V/ms for V
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.
