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.
