TPS544B28EVM Converter Evaluation Module (EVM)

Introduction

Texas Instruments’ TPS544B28EVM is a power-converter evaluation module for assessing the TPS544B28 in a nominal 12 V bus system. The board provides a regulated 1 V output with load capability up to 20 A, giving designers a ready-made platform for examining a high-current point-of-load conversion implementation rather than beginning with a custom test board.

The module is also notable for exposing both PMBus functionality and TPS544B28 pin-strap settings through onboard connectors and jumpers.

What it does

The TPS544B28EVM is intended to help users quickly set up and become familiar with the TPS544B28. It accepts a nominal 12 V input bus and generates a regulated 1 V output for loads of up to 20 A.

Connectors, jumpers, and test points are provided to support evaluation of the converter and its configurable operating modes. The board demonstrates PMBus operation, allowing users to investigate the device’s PMBus-related functionality, while pin-strap settings can be examined through the module’s hardware configuration options.

The EVM evaluates the TPS544B28, which is supplied in a 19-pin WQFN-HR package.

Applications

Potential uses for the evaluation module include:

• Evaluating 12 V-to-1 V point-of-load power conversion
• Testing regulated 1 V rails requiring up to 20 A of load current
• Exploring PMBus functionality in a converter evaluation setup
• Reviewing TPS544B28 pin-strap configuration options
• Measuring converter behavior through the board’s provided test points and connectors

Design considerations

The module is designed around a nominal 12 V input and a regulated 1 V output, so connected input supplies and loads should be selected for those operating conditions. Loads may draw up to 20 A, making load connection and test setup important considerations during evaluation.

PMBus features and pin-strap settings are exposed using connectors and jumpers. Users evaluating configuration behavior should account for the board’s installed jumper and connector settings as part of their test arrangement. The TPS544B28 device under evaluation uses a 19-pin WQFN-HR package.
