Description
The TPS53316EVM-075 is designed to use a 3.3-V or 5-V voltage rail to produce a regulated 1.5-V output
at up to 5-A load current. The TPS53316EVM-075 is designed to demonstrate the TPS53316 in a typical
low voltage application while providing a number of test points to evaluate the performance of the
TPS53316.
