PRODUCTION DATA.
| PIN | I/O(1) | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| BOOT | 6 | O | A 30-Ω boot resistor and a 0.1-μF bootstrap cap are required between BOOT and SW. The voltage on this cap carries the gate drive voltage for the high-side MOSFET. |
| EN | 5 | I | Enable pin. Float to enable. Adjust the input undervoltage lockout with two resistors. |
| FB | 4 | I | Converter feedback input. Connect to output voltage with feedback resistor divider. |
| GND | 1 | G | Ground pin. Source terminal of low-side MOSFET as well as the ground terminal for controller circuit. Connect sensitive FB to this GND at a single point. |
| SW | 2 | O | Switch node connection between high-side MOSFET and low-side MOSFET. |
| VIN | 3 | I | Input voltage supply pin. The drain terminal of high-side MOSFET. |
