The EVAL5980 evaluation boards are specifically designed to provide both designers and engineers with a rapid, low cost, and easy to use platform for evaluating power conversion products for use in DC/DC and AC/DC (off-line) SMPS applications. The EVAL5980 evaluation boards are of a modular type and are the perfect solution for both power controllers and power supplies.

The EVAL5980 features an integrated PFC front end, a fully regulated output voltage, and a wide range of output power. The EVAL5980 is capable of providing both single ended and dual outputs with adjustable output voltage from 0.9V to 7.0V and output currents of up to 25A. It also has an adjustable start up and switching frequency of up to 1MHz. The board also comes with an adjustable feedback loop, support for synchronous rectification, and a security lockout feature for protecting sensitive components from overvoltage and overcurrent conditions.

The EVAL5980 comes with an extensive range of integrated features such as a programmable soft start, adjustable current limit, adjustable output slew rate, and various other protections. The EVAL5980 boards are designed to be used in a variety of system environments, from low cost applications to high end, high power applications. The board also provides an integrated PI loop for tight control of the output voltage, current limit, and output voltage adjustment.

The working principle of the EVAL5980 evaluation boards is based on the principle of the universal power interface (UPI), which is a high-efficiency current-mode controller. The UPI is a highly efficient two-wire current regulator that offers both increased stability and improved accuracy. The working principle of the UPI includes the regulation of output voltage, current and power, as well as the ability to switch the power in the load according to user requirements.

In the operation of the EVAL5980, the UPI model is used to control and regulate the output voltage and current. The PI loop of the UPI is used to correct the power factor and provide the best possible operation for both horizontal and vertical mode loads. The UPI also improves the efficiency of the converter by utilizing power lost in the synchronous rectification process and helps to reduce the amount of heat produced by the converter. Lastly, the UPI provides an integrated output voltage regulation for improved performance and reduced EMI (electromagnetic interference) from the converter.

The EVAL5980 evaluation boards are designed to provide reliable power conversion solutions for DC/DC and AC/DC (off-line) SMPS applications. Featuring an integrated PFC front end, a wide range of output power, adjustable start up and switching frequency, and various other features, the EVAL5980 boards provide designers and engineers with a complete power conversion solution. Engineers and designers can quickly and easily evaluate the performance of the boards in their particular application and take advantage of the integrated features to accurately design a customized power package for their specific application requirements.
