Description |
| 1 | SW | Switch pin. Connect inductor/diode here. The output voltage can go up to 29V but should not exceed this limit. If the voltage on this pin is higher than the overvoltage threshold, the device can go into shutdown mode. |
| 2 | GND | Ground |
| 3 | FB | Feedback pin. Internally compares to 1.25v. Connect R1 and R2 resistor divider here. Calculate the output voltage according to the formula VOUT = 1.25V*(1+R1/R2)) |
| 4 | SHDN(ACTIVE LOW) | Shutdown pin. Connect to 1.5v or higher to enable device, 0.4V or lower to disable device. |
| 5 | VIN | Input supply pin. Must be locally bypassed |
