Table 4-1 Pin Functions
PIN TYPE(1) DESCRIPTION
NAME NO.
VIN 1 P Input voltage supply pin. Connect the input decoupling capacitors between VIN and GND.
SW 2 P Switch node pin. Connect the output inductor to this pin.
GND 3 G GND pin for the controller circuit and the internal circuitry.
BST 4 P Connect a 100nF ceramic capacitor from this pin to the SW pin or leave the pin floating.
EN 5 A Enable control input. Driving EN high enables the converter.
FB 6 A Converter feedback input. Connect to output voltage with a feedback resistor divider.
(1) A = Analog, P = Power, G = Ground
