DESCRIPTION
NAME NO.
BOOT 6 O
Supply input for the high-side NFET gate drive circuit. Connect a 0.1-μF capacitor between BOOT and
SW pins.
EN 5 I This pin is the enable pin. Float the EN pin to enable.
FB 4 I Converter feedback input. Connect to output voltage with feedback resistor divider.
GND 1 –
Ground pin Source terminal of low-side power NFET as well as the ground terminal for controller
circuit. Connect sensitive VFB to this GND at a single point.
SW 2 O Switch node connection between high-side NFET and low-side NFET.
VIN 3 – Input voltage supply pin. The drain terminal of high-side power NFET.
