1 Description

The TPS53819AEVM-123 is designed to use a regulated 12-V bus to produce a regulated 1.2-V output at up to 25 A of load current. The TPS53819AEVM-123 is designed to demonstrate the TPS53819A in a typical low voltage application while providing a number of test points to evaluate the performance of the TPS53819A.
