Product Details

The MAX20461 evaluation kit (EV kit) demonstrates the MAX20461 automotive high-current, high-efficiency, step-down DC-DC converter with integrated USB Type-C DFP controller and 1GHz bandwidth USB 2.0 D+/D- protection switches, which provide ESD and short-to-battery protection for low-voltage transceivers.

The MAX20461 features integrated host-charger port-detection circuitry that adheres to the USB Type-C specification, the USB-IF BC1.2 battery-charging specification, Apple iPod/iPhone/iPad^® and Samsung^® charge-detection termination resistors, and Chinese Telecommunication Industry Standard YD/T 1591-2009.

The MAX20461 integrates high-side current sensing and voltage adjustment circuitry, which provides automatic USB voltage adjustment to compensate for voltage drops in captive cables associated with automotive applications.

The MAX20461 step-down, synchronous, DC-DC converter operates from a voltage of up to 28V continuous and protects against load-dump transients up to 40V. The converter is programmable for frequencies from 275kHz to 2.2MHz and can deliver 3A continuously.

The EV kit contains an I²C-enabled MAX20461. The I²C interface 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 EV kit is configured for 2.2MHz operation. The data switches of the MAX20461 generally do not require far-eye tuning; the EV kit is populated with shorts.
