Pin Functions
DESCRIPTION
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.
Switch node connection between high-side NFET and low-side NFET.
Input voltage supply pin. The drain terminal of high-side power NFET.
Power good open drain output
Soft-start control. An external capacitor should be connected to GND.
Converter feedback input. Connect to output voltage with feedback resistor divider.
Enable input control. Active high and must be pulled up to enable the device.
Supply input for the high-side NFET gate drive circuit. Connect 0.1 µF capacitor between VBST and SW pins.
