Table 1. Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO | ||
| VIN | C3 | IN | Input voltage supply pin of the module. |
| GND | C2 | - | Ground terminal. |
| CTRL | B2 | IN | CTRL pin controls the LOAD output pin. With CTRL = low, the LOAD output is disabled. This pin must be terminated and not left floating. |
| VOUT | C1 | OUT | Output voltage pin of the module. An internal load switch is connected between VOUT pin and LOAD pin. |
| LOAD | B1 | OUT | Load switch output pin controlled by the CTRL pin. With CTRL = high, an internal load switch connects the LOAD pin to the VOUT pin. The LOAD pin allows connect / disconnect other system components to the output of the DC/DC converter. This pin is pulled to GND with the CTRL pin = low. The LOAD pin features soft switching. If not used, leave the pin open. |
| VSEL3 | A1 | IN | Output voltage selection pins. See Table 2 and Table 3 for VOUT selection. These pins must be terminated and can be changed during operation. |
| VSEL2 | A2 | IN | |
| VSEL1 | A3 | IN | |
| EN | B3 | IN | High level enables the devices and low level turns the device into shutdown mode. This pin must be terminated and not left floating. |
