Product Details

The MAX16984A evaluation kit (EV kit) demonstrates the MAX16984A automotive high-current, high-efficiency, step-down DC-DC converter with integrated USB Type-A controller. In addition, the device also includes 1GHz bandwidth USB 2.0 D+/D- protection switches which pro- vide ESD and short-to-battery protection for low-voltage transceivers.

The MAX16984A features integrated host-charger port- detection circuitry adhering to the USB 2.0 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 MAX16984A integrates high-side current sensing and voltage adjustment circuitry to provide automatic USB voltage adjustment to compensate for voltage drops in captive cables associated with automotive applications. The MAX16984A step-down, synchronous, DC-DC con- verter 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 310kHz to 2.2MHz and can deliver 3A continuously.

The EV kit is populated with a MAX16984AATJB/V+ con- figured for 2.2MHz operation. The data switches of the MAX16984A generally do not require far-eye tuning; the EV kit is populated with shorts.
