Evaluation and Demonstration Boards and Kits offer an engineer or hobbyist a quick and easy way to evaluate hardware in their application or understand and see how chips interact with other components. The ISL9519CEVAL1Z Evaluation board from Intersil is one such board that allows engineers to quickly test various applications.

The ISL9519CEVAL1Z Evaluation board is constructed on a rigid, two-layer FR4 with a double conforming copper design. The printed circuit board top layer houses two groups of components in configurations that simulate three different adjustable buck regulator solutions. On the bottom layer, users can find additional components such as capacitors, resistors, and diodes that work with the ISL8120M controller IC to facilitate the buck regulator circuits.

The ISL9519CEVAL1Z Evaluation board features an adjustable input voltage regulator between 12V and 36V, a wide range of switching frequencies between 150kHz and 600kHz, adjustable output voltage of 0.8V to 5V, and an output current up to 3.5A. It also features switches for changing the programming of the components on the board and the buck output can be changed with adjustable resistors and capacitors. The board also includes a micro USB connector for powering it from a computer.

The board’s operating principle relies on the ISL8120M controller IC. The IC provides Digital Pulse Width Modulation (PWM) control of the buck output voltage by monitoring the output using a sense current. This output voltage is regulated by a feedback loop that compares the output voltage with a reference voltage and sets the duty cycle of the output PWM signal accordingly.

The ISL9519CEVAL1Z Evaluation board is ideal for evaluating DC-DC buck regulator circuits and simulating general power supply designs. It can be used for applications such as distributed power systems, embedded computing systems, voltage regulators, portable equipment, and more. With its adjustable input and output voltage, adjustable frequency and current output, it is suitable for a wide range of applications.

In conclusion, the ISL9519CEVAL1Z Evaluation board from Intersil is a great tool for investigating and simulating DC-DC buck regulator circuits. With its adjustable input and output voltage, adjustable switching frequency, adjustable output current, and additional features such as micro USB connector, it is ideal for understanding and solving complex circuit issues. Engineers or hobbyists can use the board to test their applications and designs with ease.
