Analog Devices / Maxim Integrated MAX20461 Evaluation Kit

Analog Devices Inc. MAX20461 Evaluation Kit is configured to evaluate the operation of the MAX20461 automotive high-current, high-efficiency, step-down DC-DC converter. The MAX20461 Evaluation Kit contains an I2C-enabled MAX20461.

The I2C interface on the kit allows for flexible configuration, detailed fault diagnostics, and access to the on-chip ADC that reports die temperature, output voltage, and output current. The I2C features are easily accessed using the Maxim MINIQUSB module and the provided example GUI. The Evaluation Kit is designed for 2.2MHz operation. The data switches of the MAX20461 generally do not require far-eye tuning, and the kit is populated with shorts.
