NCV896530  
2.1 MHz Low Voltage Dual  
Output Buck Converter  
The NCV896530 dual stepdown dcdc converter is a monolithic  
integrated circuit dedicated to automotive driver information systems  
from a downstream voltage rail.  
http://onsemi.com  
MARKING DIAGRAM  
Both channels are externally adjustable from 0.9 V to 3.3 V and can  
source totally up to 1600 mA. Converters are running at 2.1 MHz  
switching 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 in  
automotive power systems such as integrated softstart,  
cyclebycycle current limit and thermal shutdown protection. The  
device can also be synchronized to an external clock signal in the  
range of 2.1 MHz.
