Single Synchronous Step-Down Controller

for Low-Voltage Power Rails

1 Introduction

The TPS53015EVM-126 evaluation module (EVM) presents an easy to use reference design for a typical

point-of-load application in a stand-alone module using the TPS53015 controller in cost sensitive

applications.

2 Description

The TPS53015EVM-126 provides the user with a convenient way to evaluate the TPS53015 D-CAP2™

mode control in a cost sensitive application. Providing a 1.05-V output at up to 8 A from a loosely

regulated 12 V (8 V – 22 V) source, the TPS53015EVM-126 is designed to demonstrate the TPS53015 in

a typical point-of-load application while providing a number of test points to evaluate the performance of

the TPS53015.

2.1 Typical Applications

• Point-of-Load Regulations in Low-Power Systems for Wide Range of Applications

– Digital TV Power Supply

– Network Home Terminals

– Digital Set Top Box (STB)

– DVD Player/Recorder

– Game Consoles and Others

2.2 Features

The TPS53015EVM-126 features:

• D-CAP2™ Mode Control

– Fast Transient Response

– No External Parts Required For Loop Compensation

– Compatible with Ceramic Output Capacitors

• Auto-Skip Eco-mode™ for High Efficiency at Light load

• 500-kHz switching frequency

• Power Good Indication

• Non-Sinking Pre-Biased Soft Start

• Cycle-by-Cycle Over-Current Limit

• Over-current, over-voltage, under-voltage and over-temperature protections

• Convenient test points for probing critical waveforms
