Functional Pin Description
Pin No.
Pin Name
Pin Function
1
GND
Power ground.
2
SW
Switch node between the internal switch and the synchronous rectifier.
Connect this pin to the inductor and bootstrap capacitor.
3
VIN
Power input. The input voltage range is from 4.5V to 18V. Connect input
bypass capacitors directly to this pin and GND pins. The MLCC with
capacitance higher than 20
F is recommended.
4
FB
Feedback voltage input. Connect this pin to the midpoint of the external
feedback resistive divider to set the output voltage of the converter to the
desired regulation level. The device regulates the FB voltage at feedback
reference voltage, typically 0.765V.
5
EN
Enable control input. Connect this pin to logic high enables the device and
connect this pin to GND disables the device.
6
BOOT
Bootstrap capacitor connection node to supply the high-side gate driver.
Connect a 0.1
F ceramic capacitor between this pin and the SW pin.
