The TPS65214EVM has multiple headers that can be used to change the input supply for some of the power rails. The PCB also includes headers that allows changing specific functions of the PMIC using the multi-function pins. Table 2-4 lists all the headers and the expected configuration for each selection. For reference, the header locations and configuration options are shown in Figure 2-3.
| Header Name | Description | Configuration | |
|---|---|---|---|
| J6 | PRE_REG/EXT_SUPPLY | VSYS Input source selection | J6-1, J6-3 VSYS supplied by PRE-REG output (3.3V / 5V) |
| J6-5, J6-7 VSYS supplied by external supply at VSYS input (J5) | |||
| J7 | USB_5V | VSYS Input source selection | J7-1 VSYS supplied by USB input |
| J8 | VIO | VIO source select | J8-1 VIO supplied by external 3.3V LDO |
| J8-3 VIO supplied by BUCK2 output | |||
| J11 | GPIO_VSEL | High/Low selection for GPIO/VSEL pin | J11-1 Sets GPIO/VSEL pin HIGH. Effect is dependent on configuration as GPIO or VSEL |
| J11-3 Sets GPIO/VSEL pin LOW. Effect is dependent on configuration as GPIO or VSEL | |||
| J14 | MODE_STBY | High/Low selection for MODE/STBY pin | J14-3 Sets MODE/STBY pin HIGH. Effect is dependent on configuration as MODE, STBY, or both |
| J14-1 Sets MODE/STBY pin LOW. Effect is dependent on configuration as MODE, STBY, or both | |||
| J30 | EXT_LDO_VIN | External 3.3V LDO Input | External LDO supplied by VSYS |
| J31 | PMIC_EN | PMIC enable | PMIC enable pin if EN/PB/VSENSE is configured as EN |
