Texas Instruments TPS544x25EVM-681 Evaluation Board
Texas Instruments TPS544x25EVM-681 Evaluation Boards are to demonstrate either the TPS544B25 or TPS544C25 synchronous buck converters in typical low voltage applications. The evaluation boards are designed as a single output DC-DC converter that demonstrates a typical low-voltage application. It does this while providing a number of test points to evaluate the performance. It uses a nominal 12V input bus to produce a regulated 0.95V output at up to 20A of load current, depending on the device installed.
