Analog Devices / Maxim Integrated MAX20459EVKIT Evaluation Kit

Analog Devices MAX20459EVKIT Evaluation Kit is designed to quickly and easily demonstrate the MAX20459. The MAX20459 Automotive High-Current Step-Down Converter integrates a 3A high-efficiency, automotive-grade, step-down converter, a USB Type-C DFP controller, and automatic BC1.2 DCP, Apple®, plus Samsung® dedicated charger-detection circuitry.

The ADI MAX20459EVKIT Evaluation Kit provides a standalone enabled MAX20459ATJC/V+ that is configured by pull-down resistors. The I2C variant (MAX20459ATJA/V+) 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 reached by using the ADI MINIQUSB module along with the provided example GUI.
