The SXQ50 series are surface mount high-efficiency, isolated DC/DC converters in a
standard quarter-brick format and a height of just 0.4 inches. The converters provide up to
50 Watts of output power and are capable of delivering very high current at low voltages.
Patent pending technology ensures unprecedented levels of performance from a 50W
surface-mount DC/DC converter. 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 SXQ50 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, SXQ50 series converters reduce compliance costs and time to market.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
