SLVUAF6A June 2015 – May 2021 TPS62745
| J1 – VIN | Positive input connection from the input supply for the EVM (3.3 V to 10 V) |
| J2 – S+/S- | Input voltage sense connections. Measure the input voltage at this point. |
| J3 – GND | Return connection from the input supply for the EVM. |
| J4 – VOUT | Output voltage connection. |
| J5 – S+/S- | Output voltage sense connections. Measure the output voltage at this point. |
| J6 – GND | Output return connection. |
| J7 – PG/GND | The PG output appears on pin 1 of this header with a convenient ground on pin 2. |
| J8 – VIN_SW | VIN switch output connection. |
| J9 – SW/GND | Switch Node sense connection. |
| JP1 – EN | EN pin input jumper. Place the supplied jumper across ON and EN to turn on the IC. Place the jumper across OFF and EN to turn off the IC. |
| JP2 – EN_VIN_SW | Enable VIN switch jumper. Place the supplied jumper across VIN_SW_ON and EN_VIN_SW to activate (close) the internal VIN switch. Place the jumper across VIN_SW_OFF and EN_VIN_SW to de-activate (open) the internal VIN switch. |
| JP3 through JP6 – VSELx | These four inputs set the output voltage. By connecting each pin high or low, the output voltage is programmed per Table 2-1. Do not leave any jumper open for proper operation. |
Table 2-1 provides the output voltage settings for the TPS62745EVM-622. A 0 refers to logic low, while 1 refers to logic high.
