Texas Instruments  TPS53353EVM-744

The TPS53353EVM-744 evaluation module (EVM) demonstrates the TPS53353. The TPS53353 is a D-CAP™mode, 20-A, synchronous buck converter with integrated MOSFETs. It provides a fixed 1.5-V output at up to 20 A from a 12-V input bus. The TPS53353EVM-744 is designed to use a regulated 12-V bus to produce a regulated 1.5-V output at up to 20 A of load current. The TPS53353EVM-744 is designed to demonstrate the TPS53353 in a typical low-voltage application while providing a number of test points to evaluate the performance of the TPS53353.
