TPS54110EVM-044

A Texas Instruments TPS54110EVM-044 Evaluation Board provides an easy and cost-effective way to evaluate the performance of a TPS5410 family of isolated DC/DC step-down converters. This evaluation board can be used to demonstrate the power transfer efficiency and accuracy of the TPS5410 in a variety of applications including automotive, industrial, medical and communications systems. The board contains a pre-programmed TPS5410 to generate an 8 V power output when hooked up to an AC mains input and a resistive load.

The evaluation board is designed to evaluate the power transfer efficiency of Texas Instruments TPS5410 family of isolated DC/DC step-down converters. The board is configured to deliver 8V ±1V 150W output when driven by an AC input of 85-265V and a resistive load. The evaluation board includes the TPS5410EVM-044 switching regulator, a control loop with adjustable settings for control, synchronization and loop compensation, COMS thermistor, temperature sensing, and load regulation.

The primary function of the TPS5410EVM-044 is to convert an unregulated AC input voltage of 85VAC to 265VAC into a regulated DC output voltage. The evaluation board includes both a primary-side and secondary-side synchronous rectifiers to increase power efficiency. These rectifiers are driven by current-sensing comparators in order to control the conduction period of the synchronous rectifiers. The evaluation board also includes a control loop with an adjustable frequency and current-mode control for optimum load line regulation.

The evaluation board also includes robust protections for overcurrent, overvoltage and over temperature conditions. It also provides a temperature sensor for system-level monitoring. Furthermore, the evaluation board contains a COMS thermistor for temperature sensing and load regulation. The COMS thermistor is thermally coupled to the heat sink, thus providing a temperature guide for the evaluation board. As such, it allows users to adjust the switching frequency of the converter to increase system efficiency and reduce component stress.

In conclusion, the TPS5410EVM-044 evaluation board provides an easy and cost-effective way to evaluate the performance of a TPS5410 family of isolated DC/DC step-down converters. The evaluation board provides users with the ability to evaluate the power transfer efficiency of the TPS5410 in a variety of applications. The board includes features such as voltage, current, and temperature monitoring, synchronous rectifiers control, and loop compensation which help ensure the best performance and accuracy when evaluating the TPS5410 family of isolated DC/DC step-down converters.
