EXQ50 Series Single output DC/DC CONVERTERS 36-50W High Efficiency DC/DC Converters 1 • • • • High efficiency topology, 90% at 5V and 86.5% typical at 1.8V Low profile, open-frame package Industry standard footprint Wide operating temperature, -40°C to +90°C (with derating) • 90% to 110% output trim • No minimum load • Remote on/off 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.

Significant reduction possible with external filter. 6 Start-up into resistive load. 7 Active low remote On/Off is available. Standard product is active high. When ordering active low parts, designate with the Suffix '-R', e.g EXQ50-48S3V3-R. 8 This parameter is calculated at worst case line, load, temperature and initial settings. 9 This is inclusive of the output trim range. If 6.0% trim-up is used, for example, then only 4.0% output sense is available. 10 Maximum, not typical, specification. 0.400±0.017 (10.18±0.44) Installed HT 1 UL/cUL CAN/CSA 22.2 No. 60950-00 : UL 60950 File No. E174104 TÜV TÜV Product Service.
