Table 4-1 Pin Functions
PINTYPE(1)DESCRIPTION
NAMEDDC NO.
SW1PWRThe switch pin of the converter. This pin is connected to the drain of the internal power MOSFET.
GND2GGround
FB3IVoltage feedback of output voltage. Connected to the center tap of a resistor divider to program the output voltage.
EN4IEnable logic input. Logic high voltage enables the device. Logic low voltage disables the device and turns the device into shutdown mode.
VIN5IIC power supply input
(1) I = Input, G = Ground, PWR = Power
