1.2 Alternate Board Configurations

If a custom configuration is desired, users should refer to the TPS7H2211-SP data sheet to calculate the values of the passive components around the device and note any operational requirements.

In addition to the default EVM configuration, this user's guide provides an example for how the TPS7H2211EVM-CVAL may be configured for parallel operation. The enable (EN) and overvoltage protection (OVP) specifications for the parallel configuration are the same as what is used for the default configuration. However, this configuration is capable of providing up to double the output current compared to the default configuration.

More detailed information about the parallel EVM configuration can be found in the Parallel Configuration Schmatic and the Parallel Configuration Bill of Materials.
