| SXQ50 Series DC/DC CONVERTERS Single output 36-50W High Efficiency DC/DC Converters 1 * Surface mount quarter-brick format * High efficiency topology, 90% at 5V and 86.5% typical at 1.8V * Low profile, open-frame package * Wide operating temperature, -40C to +90C (with derating) * 90% to 110% output trim * No minimum load * Remote on/off 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 (TUV 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 25C unless otherwise stated TUV 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Total error band Set point accuracy Line regulation Load regulation Voltage adjustability Output remote sense range Minimum load Overshoot Undershoot Ripple and noise Transient response (See Note 1) INPUT SPECIFICATIONS Input voltage range Input current Input current (max.)

See Application Note 120 for details. 3 Recommended input fusing is a 3.15A HRC 200V rated fuse. 4 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 5 Measured with no external Pi filter. 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 SXQ50-48S3V3-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. 11 To order an Evaluation Kit which contains a SXQ50 model pre-mounted on a circuit card with test points for easy testing in the laboratory, please add the suffix `-EVAL' to the model number, e.g. SXQ50-48S05-EVAL. Please see the SXQ50 Evaluation Board User Guide for further details. 1 CAUTION: Hazardous internal voltages and high temperatures. Ensure that unit is not user accessible.
