EXQ50 series high-efficiency, open-frame, isolated DC/DC converters have an industry
standard quarter-brick footprint and a height of just 0.4 inches. The converters provide
up to 50 Watts of output power, are capable of delivering very high current at low
voltages, and offer exceptional power densities for today’s high-end applications. The
first four models in the series feature an input voltage range of 33 to 75VDC and are
available with output voltages of 5.0V, 3.3V, 2.5V or 1.8V. The output voltage of each
model is adjustable from 90% to 110% of its nominal value. Typical efficiencies are
90% for the 5V model, 89% for the 3.3V, 88% for the 2.5V and 86.5% for the 1.8V. All
EXQ50 series converters have a remote on/off capability, and are fully protected against
over-voltage, over-temperature and short-circuit conditions. Featuring full international
safety approval, including EN60950 (TÜV Product Service) and UL/cUL 60950, EXQ50
series converters reduce compliance costs and time to market.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
