Pin Functions

PIN I/O DESCRIPTION
NAME NO.
GND 2 Ground. This is the return current path for the power stage of the device. Connect this pin to the bypass capacitors associated with VIN and VOUT.
VIN 1 I Input Voltage. This pin supplies voltage to the control circuitry and power switches of the converter. Connect external bypass capacitors between this pin and GND.
VOUT 3 O Output Voltage. This pin is connected to the internal output inductor. Connect this pin to the output load and connect external bypass capacitors between this pin and GND.
