MARKING DIAGRAM
NCV896530
The NCV896530 dual step−down dc−dc converter is a monolithic
integrated circuit dedicated to automotive driver information systems
from a downstream voltage rail.

ALYWG
G
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 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 NCV896530 is available in a space saving, 3 x 3 mm 10−pin
DFN package.
