PRODUCTION DATA
PIN | TYPE(1) | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
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 | I | Input voltage supply pin. The drain terminal of high-side power NFET. |
VFB | 4 | I | Converter feedback input. Connect to output voltage with feedback resistor divider. |
EN | 5 | I | Enable input control. Active high and must be pulled up to enable the device. |
VBST | 6 | O | Supply input for the high-side NFET gate drive circuit. Connect 0.1 µF capacitor between VBST and SW pins. |
