Ground.
Enable control input.
Converter feedback input. Connect to output voltage feedback resistor divider.
No internal connection.
Soft-start control. A external capacitor should be connected to GND.
5V power supply output. A capacitor (typical 1F) should be connected to GND.
Open drain power good output.
Power input and connected to high-side MOSFET drain.
Bootstrap. This capacitor is needed to drive the power switch's gate above the
supply voltage. It is connected between SW and BOOT pins to form a floating
supply across the power switch driver. A 0.1F capacitor is recommended for use.
Switch output.
