STEVAL-ISA071V2 - Highly Efficient Power Conversion Evaluation Board

The STEVAL-ISA071V2 from STMicroelectronics is a state-of-the-art evaluation board designed for those looking to explore the capabilities of advanced power conversion technologies. This compact and versatile board is specifically tailored for testing the performance of the L6563H, which is a high-efficiency zero-voltage switching (ZVS) resonant controller. It is an ideal solution for engineers and designers focusing on developing high-efficiency power supplies, particularly in applications such as LCD and LED TVs, server and telecom power supplies, and silver box PC SMPS.

The board is built to demonstrate the functionality of a 150 W, wide-range mains input, and a 12 V output converter. It utilizes a resonant topology that ensures reduced electromagnetic interference (EMI) and higher power density, making it suitable for a variety of demanding applications. The L6563H controller on the board is compatible with both half-bridge and full-bridge topologies, providing flexibility for different design requirements.

Key features of the STEVAL-ISA071V2 include its ability to operate at high switching frequencies, which significantly reduces the size of the power supply components, leading to a more compact and lightweight design. The evaluation board also showcases the controller's CrM (Critical conduction Mode) and CCM (Continuous Conduction Mode) operation that helps in achieving high efficiency across a wide load range.

Furthermore, the STEVAL-ISA071V2 is equipped with numerous protection features to ensure safe operation under various conditions. These include over-voltage, over-current, and thermal protection, which not only safeguard the board itself but also provide insights into how these protective measures can be implemented in a final product design.

STMicroelectronics provides comprehensive technical documentation for the STEVAL-ISA071V2, including schematics, bill of materials, and application notes, which enables designers to rapidly understand and integrate the board into their prototypes or evaluate it for their specific applications. With its high efficiency, flexible design options, and robust protection features, the STEVAL-ISA071V2 is an invaluable tool for developers working on cutting-edge power conversion solutions.
