| EXQ125 Series DC/DC CONVERTERS * Ultra-high efficiency topology, 91% at 3.3V, 88% typical at 1.8V * Industry standard footprint * Wide baseplate temperature, -40C to +100C * 90% to 110% output trim * No minimum load * Overvoltage protection * Remote on/off Single output 36-100W 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 to 75VDC and are available in output voltages of 12V, 5V, 3.3V, 2.5V, 1.8V, 1.5V and 1.2V. 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 (TUV Rheinland) and UL/cUL1950, the EXQ125 reduces compliance costs and time to market.

Deviation varies by model, see Long Form Data Sheet. The EXQ125 meets level A and level B conducted emissions only with external components connected before the input pins to the converter. See Application Note 118. Recommended input fusing is a 5A HRC 200V rated fuse. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Measured with no external Pi filter. Significant reduction possible with external filter. See Application Note 118. Start-up into resistive load. Active low remote On/Off is available. Standard product is active high. When ordering active low parts, designate with the Suffix `-R', e.g EXQ125-48S3V3-R. When ordering 0.145" pin lengths designate with the Suffix `-N', if the product is already a `-R' suffix product then the suffix will be `-RN' When ordering 0.110" pin lengths designate with the Suffix `-K', if the product is already a `-R' suffix product then the suffix will be `-RK' CAUTION: Hazardous internal voltages and high temperatures. Ensure that unit is not user accessible.
