PRODUCTION DATA
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NAME | NO. | ||
VIN | 1 | I | Input voltage supply pin |
SW | 2 | O | Switch node connection between high-side NFET and low-side NFET |
GND | 3 | — | Ground pin Source terminal of low-side power NFET as well as the ground terminal for controller circuit. Connect sensitive FB to this GND at a single point. |
BST | 4 | O | Supply input for the high-side NFET gate drive circuit. Connect 0.1-µF capacitor between BST and SW pin. |
EN | 5 | I | Enable input control. Active high and must be pulled up to enable the device. |
FB | 6 | I | Converter feedback input. Connect to output voltage with feedback resistor divider. |
