XR76205EVB-Q is an evaluation board designed for DC/DC & AC/DC (Off-Line) SMPS. It offers a complete, easy-to-use platform for evaluating the performance of the XR7620E controller with its proprietary quasi-resonant (QR) topology for the development of SMPS applications. This evaluation board helps designers to quickly design and evaluate products such as desktop and laptop computer power adapters, LCD TVs, LED lighting, and other consumer and industrial applications.

XR76205EVB-Q provides a comprehensive evaluation platform designed specifically for the XR7620E. It offers an analytical scope of features for testing and characterizing the XR7620E, including adjustable push-pull voltage feedback and remote sense when working in discontinuous conduction mode (DCM). The board also has comprehensive LED and LCD displays for monitoring the operating parameters.

At the heart of the XR7620E sits its proprietary QR topology, which offers various advantages over traditional resonant switching approaches. The primary advantage is a reduction in EMI and eliminating the need for external components to suppress radiofrequency emissions. Additionally, QR switching allows for increased power transfer efficiency and improved power quality by providing highly accurate and consistent constant-current or constant-voltage regulation over the entire load range. This leads to improved design, increased system reliability, and lower total system costs.

The XR76205EVB-Q assists designers in generating the optimal designs for their applications in the shortest possible time. It provides designers with a comprehensive suite of tools for evaluating the performance of the XR7620E, including adjustable push-pull voltage feedback, remote sense in DCM, and LED & LCD displays for monitoring operating parameters. The board is also designed to be easily expanded into system evaluation with optional circuit add-ons.

Also, the XR76205EVB-Q includes various accessories such as an external heatsink, an adjustable input voltage range, and thermal protection. The external heatsink provides greater airflow for improved thermal performance, while the adjustable input voltage range (4.5V to 28V) ensures compatibility with various input sources. Moreover, the board provides protection against overvoltage and overtemperature conditions, helping to prevent damage to the XR7620E in the event of an unexpected input fault.

In conclusion, XR76205EVB-Q is a complete evaluation board for DC/DC and AC/DC (Off-Line) SMPS applications. It provides all the necessary components for evaluating the behavior of the XR7620E controller as well as a comprehensive suite of features for monitoring operating conditions. Additionally, the board’s protective features and optional circuit add-ons help ensure reliability and faster design time for emerging applications.
