描述

MAX16984L evaluation kit (EV kit) demonstrates the MAX16984L automotive high-efficiency step-down DC-DC converter with integrated USB protection and host charger adapter.

The MAX16984L features integrated host-charger portdetection 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 dedication charging modes.

The MAX16984L 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 MAX16984L step-down DC-DC converter operates from a voltage of up to 28V continuous and is protected from load dump transients to 42V. The converter is resistor- programmable for frequencies from 220kHz to 2.2MHz 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 MAX16984L. 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 high-speed eye diagram for this EV kit is shown in Figure 1.
