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. |
