NCV894630

2 A - 2.1 MHz High

Efficiency Low Voltage

Step-Down Converter

The NCV894630 step−down dc−dc converter is a monolithic

integrated circuit dedicated to automotive driver information systems

from a downstream voltage rail. The output voltage is externally

adjustable from 0.9 V to 3.3 V and can source up to 2 A. The converter

is running at a 2.1 MHz switching frequency, above the sensitive AM

band. The NCV894630 provides additional features expected in

automotive power systems such as integrated soft−start, hiccup mode

current limit and thermal shutdown protection. The device can also be

synchronized to an external clock signal in the range of 2.1 MHz. The

NCV894630 is available in the same 3x3 mm 10−pin DFN package as

the dual NCV896530, with compatible pin−out.
