Introduction
The TPS53119EVM-690 evaluation module (EVM) uses the TPS53119 device. The TPS53119 is a small-
size, single buck controller with adaptive on-time D-CAP™ mode control. It provides a fixed 1.1-V output
at up to 25 A from a 12-V input bus. TPS53119EVM-690 also uses the 5-mm × 6-mm TI power block
MOSFET (CSD86350Q5D) for high power density and superior thermal performance.

Description
The TPS53119EVM-690 is designed to use a regulated 12-V bus to produce a regulated 1.1-V output at
up to 25 A of load current. The TPS53119EVM-690 is designed to demonstrate the TPS53119 in a typical
low-voltage application while providing test points to evaluate the performance of the TPS53119.
