Default Board Configuration

The EVM is designed to be used across the entire input voltage and output current range of the TPS7H2211-SP while providing flexibility to configure the device to operate under different conditions. By default, the EVM is configured for a single device as summarized in Table 1-1, but the board provides footprints that can be populated with an additional device and passive components to allow for testing of parallel or cold sparing applications.

More detailed information about the default EVM configuration can be found in the Default Configuration Schematic and the Default Configuration Bill of Materials.
