TPS53317EVM-750 D-CAP+™ Mode Synchronous

Step-Down Integrated FETs Converter

1 Introduction

The TPS53317EVM-750 evaluation module (EVM) is a synchronous buck regulator featuring TPS53317.

The TPS53317 is a fully integrated synchronous buck regulator employing D-CAP+™ technology.

2 Description

The TPS53317EVM-750 is designed to use a 1.5-V voltage rail to produce a regulated 0.75-V or use a

1.35-V voltage rail to produce a regulated 0.675-V output at up to 6-A load current. The

TPS53317EVM-750 is designed to demonstrate the TPS53317 in a typical low voltage application while

providing a number of test points to evaluate the performance of the TPS53317.

2.1 Typical Applications

• VTT Terminators

• Low-Voltage Applications for 1-V to 6-V Step-Down Rails

2.2 Features

The TPS53317EVM-750 features:

• Integrated Droop Support

• External Tracking Support

• Selectable Switching Frequency Settings (600 kHz and 1 MHz)

• Selectable Light-Load Operation Modes (auto-skip and forced CCM)

• Selectable Valley Overcurrent Limit

• PGOOD Function

• Convenient Test Points for Probing Critical Waveforms
