Description
The TPS53317AEVM-726 is designed to use a 1.2-V voltage rail to produce a regulated 0.6-V output at up
to 6-A load current. The TPS53317AEVM-726 is designed to demonstrate the TPS53317A in a typical low
voltage application while providing a number of test points to evaluate the performance of the
TPS53317A.
