[FAQ] DRA74: Recommended Power Solution

Part Number: DRA74

What is the recommended power solution for DRA74x, DRA75x, or TDA2x?

  • There are three recommended power configurations for the DRA74x, DRA75x, and TDA2x devices.

    1. The first configuration uses the TPS659039-Q1, TPS57112-Q1, TPS22965-Q1, and TPS51200-Q1 devices. This supports the superset DRA74x, DRA75x, and TDA2x performance, and also supports DRA7xxP and TDA2P devices running at 1.5GHz or lower.
    2. The second configuration uses the TPS659039-Q1, TPS22965-Q1, and TPS51200-Q1 devices, and supports the superset performance of the processor.
    3. The third configuration uses the TPS659039-Q1, TPS22965-Q1, and TPS51200-Q1 devices, and supports processor currents up to 3.4A on the DSPEVE + GPU + IVA rails combined. There are also two available buck regulators for external use.

    The details of these configurations are listed in the TPS659039-Q1 user’s guide for DRA74x, DRA75x, and TDA2x.

     For low-power use cases of the DRA74x, DRA75x, and TDA2x processors, the TPS65917-Q1 can be used instead, along with TPS22965-Q1 and TPS51200-Q1. The TPS65917-Q1 supports processor currents up to 3A on the MPU rail, and 3A on the DSPEVE + GPU + IVA rails combined. The details of these configurations are listed in the TPS65917-Q1 User’s Guide to Power DRA7xx and TDA2x/TDA2Ex.
