Wide Input Range Single Output DC-DC Converters
For applications requiring wide range input, improved electrical and
thermal perfomance consider Murata Power Solutions new UQQ
Series Quarter-Brick DC-DC Converters. They measure just 1.45
x 2.22 x 0.43 inches (36.8 x 56.4 x 10.92mm) and t the industry-
standard footprint.
