EXQ125 Series DC/DC CONVERTERS • Ultra-high efficiency topology, 91% at 3.3 V, 88% typical at 1.8 V • Industry standard footprint • Wide baseplate temperature, -40 °C to +100 °C • 90% to 110% output trim • No minimum load • Overvoltage protection • Remote ON/OFF • Available RoHS compliant Single output 36-100 W High Efficiency DC/DC Converters 1 The EXQ125 is a new ultra high efficiency, open-frame, isolated converter series in an industry standard quarter-brick footprint that provides up to 100 Watts of output power. The EXQ125 delivers very high output current at low voltages, and excellent useable power density for today’s high end applications. The seven models in the series feature an input voltage range of 33 Vdc to 75 Vdc and are available in output voltages of 12 V, 5 V, 3.3 V, 2.5 V, 1.8 V, 1.5 V and 1.2 V. The output voltage on each model is adjustable from 90% to 110% of the nominal value. The EXQ125 series also has a remote ON/OFF capability. Overcurrent and overvoltage protection features are included as standard. With full international safety approval including EN60950 (TÜV Rheinland) and UL/cUL1950, the EXQ125 reduces compliance costs and time to market. All specifications are typical at nominal input, full load at 25 °C unless otherwise stated TÜV 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Set point accuracy Line regulation Load regulation Minimum load Overshoot Undershoot Ripple and noise Transient response (See Note 1) INPUT SPECIFICATIONS Input voltage range Input current Input current (max.)
