描述

The MAX16984 evaluation kit (EV kit) demonstrates the MAX16984 automotive high-current step-down converter with USB protection/host charger adapter emulator.

The device features integrated host-charger port-detection circuitry adhering to the USB 2.0 BC1.2 battery charging specification and also features circuitry for Apple® iPod®/ iPhone® 1.0A and iPad® 2.1A dedicated charging modes.

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

The device’s step-down DC-DC converter operates from a voltage of up to 28V continuous and is protected from load-dump transients up to 42V. The converter is resistorprogrammable for 220kHz to 2.2MHz frequencies and can deliver 2.1A continuously.

The EV kit is configured for 2.2MHz operation, and the included 3-meter USB cable allows for demonstration of the cable-compensation capability of the device. This EV kit has been tuned for optimal eye quality at the end of the supplied USB cable; this tuning method is referred to as far-eye tuning. The USB 2.0 Hi-Speed eye diagram for this EV kit is shown in Figure 1.

The EV kit serves as a basic reference diagram for designs using the MAX16984. Component selection and layout should be closely followed to ensure optimal application performance. For additional support or design assistance, contact factory.
