6-A Step-Down Regulator with Integrated Switcher

1 Introduction

The TPS53313EVM-078 evaluation module (EVM) is a step-down regulator featuring the TPS53313. The

TPS53313 is a fully integrated step-down regulator employing voltage mode control.

2 Description

The TPS53313EVM-078 is designed to use a 12-V voltage rail to produce a regulated 1.2-V output with up

to 6-A load current. The TPS53313EVM-078 is designed to demonstrate the TPS53313 in a typical

Point-Of-Load (POL) application while providing a number of test points to evaluate the performance of

the TPS53313.

2.1 Typical Applications

• POL Applications for 5-V or 12-V Step-Down Rails
