NCV896530
2.1 MHz Low Voltage Dual
Output Buck Converter
The NCV896530 dual step down dcdc converter is a monolithic
integrated circuit dedicated to automotive driver information systems
from a downstream voltage rail.
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 lar ge 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,
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.
The NCV896530 is available in a space saving, 3 x 3 mm 10 pin
DFN package.
