STMicroelectronics STEVAL-6986YT2DL Evaluation Board

STMicroelectronics STEVAL-6986YT2DL Evaluation Board is a compact, high-efficiency Isobuck-Boost Converter evaluation board designed to showcase the performance of the A6986I synchronous monolithic step-down regulator in isolated and non-isolated configurations. Operating from a wide input voltage range of 5.5V to 38V, the STEVAL-6986YT2DL delivers a regulated output of 12V at up to 1A, making it ideal for industrial and automotive applications requiring robust, isolated power rails. The board integrates a transformer and secondary-side rectification circuitry, enabling designers to evaluate buck and boost topologies in a single platform. With features like low quiescent current, peak current mode control, and adjustable soft-start, the STMicroelectronics STEVAL-6986YT2DL offers a practical and flexible solution for developing efficient, isolated DC-DC converters.
