1 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.
