What is the recommend power solution for DRA78x or TDA3x?

  • There are two different recommended power solutions for DRA78x and TDA3x.

    1. The first configuration using TPS65919-Q1, TPS22965-Q1, and TPS51200-Q1 supports the superset TDA3x performance. The details of this configuration are listed in the TPS65919-Q1 and TPS65917-Q1 User’s Guide to Power TDA3x. Note that TPS65917-Q1 configurations are available with the same power mapping as TPS65919-Q1 but with an additional buck regulator and LDO for external use.
    2. The second configuration using LP87332A-Q1, LP87322E-Q1, TPS22965-Q1, and TPS51200-Q1 is a smaller, lower-cost solution that supports processor load currents up to 2.55A on the vdd_dspeve rail. The details of this configuration are listed in the LP87332A-Q1 and LP87322E-Q1 User’s Guide to power TDA3x.
