Onsemi NCV896530

Description

The NCV896530 dual step−down dc−dc converter is a monolithicintegrated circuit dedicated to automotive driver information systemsfrom a downstream voltage rail.Both channels are externally adjustable from 0.9 V to 3.3 V and cansource totally up to 1600 mA. Converters are running at 2.1 MHzswitching frequency above the sensitive AM band and operate 180°out of phase to reduce large amounts of current demand on the rail.Synchronous rectification offers improved system efficiency.The NCV896530 provides additional features expected inautomotive power systems such as integrated soft−start, hiccup modecurrent limit and thermal shutdown protection. The device can also besynchronized to an external clock signal in the range of 2.1 MHz.The NCV896530 is available in a space saving, 3 x 3 mm 10−pinDFN package.
