5.1 Default EVM Configuration

This section describes the default configuration programmed on the TPS6521901 PMIC.

The TPS65219EVM comes with the TPS6521901 PMIC installed which is one of the orderable part numbers of the TPS65219 device family. Table 5-1 shows the default jumper configuration that can be used to evaluate the PMIC performance. For reference, Figure 5-1 demonstrates the output voltages and jumper location on the EVM. These information is based on the programmed default configuration on the TPS6521901 NVM. The EVM can be used to evaluate other TPS65219 variants. External passive components and jumper configuration might need to be changed if the PMIC is reconfigured or replaced with a different orderable.

For more information about the settings that can be re configured and the I2C registers associated, please refer to the device data sheet and technical reference manual (TRM).

The TPS65219EVM is designed to demonstrate some of the potential uses of the PMIC family. The EVM has more limitations than the TPS65219x device.

Table 5-1 TPS65219EVM default jumper configuration
Header Jumper Default Position
Supply voltage setup J1 VIN_BUCK3 setup to supply Buck3 with VSYS
J3 VIN_LDO1 setup to supply LDO1 with BUCK2
J9 VIN_LDO2 setup to supply LDO2 with BUCK2
J10 VIN_LDO34 setup to supply LDO3/4 with BUCK2
J11 EXTLDO_VIN setup to supply the discrete 3.3V LDO with VSYS

(U2 Ref designator on schematic)

J4 I2C_SELECT setup to use the 3.3V discrete LDO as the pull-up supply for the I2C pins.
Multi-Function pin setup J5 VSEL Low = sets 1.8V output voltage on LDO1 (default EVM config)

High = sets 3.3V output voltage on LDO1 if the LDO is supplied by a 3.3V source.
J8 MODE/STBY

High = ACTIVE state (default EVM config)

Low = STBY state
J12 MODE_RESET

High = normal operation (default EVM config)

Low = performs a warm reset (reset target voltage and Bypass mode configs to their default NVM values)
