Description
Switching node tied to drain of internal N-channel MOSFET and source of internal
P-channel MOSFET. Connect this pin to the external power inductor.
No connect.
Input voltage for the controller.
Input enable pin.
Non-power signal ground pin.
Feedback input pin. This pin is connected to an external resistor divider which de-
termines the output voltage setpoint.
Power ground pin. Connect this pin directly to input and output capacitors.
Output pin; connected to the positive terminal of the output capacitor and to the
external resistor divider.
