The EXQ125 is a new high efficiency, open frame, isolated 100 Watt converter series in an industry standard quarter-brick footprint. The EXQ125 delivers very high output current at low voltages, and excellent useable output power for today's high-end applications. The design takes advantage of open-frame construction to provide a low mass, low thermal impedance baseplate design. The simplicity of the baseplate design enables customers to easily manage cooling of the product, eliminating the guesswork associated with competing products. 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. Typical efficiencies for the models are 91% for the 3.3 V, 90% for the 2.5 V, and 88% for the 1.8 V version. 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 cUL1950, the EXQ125 reduces compliance costs and time to market.

Standard product is active high. When ordering active low parts, designate with the Suffix '-R' e.g. EXQ125-48S3V3-RJ. See Application Note 118 for detailed information regarding ON/OFF control control implementation. Europe (UK) 3 When ordering 0.145" pin lengths designate with the Suffix'-N', e.g. EXQ125-48S3V3-NJ. If the product is already a 'R'suffix product then the suffix will be '-RNJ', e.g EXQ125-48S3V3-RNJ. 4 When ordering 0.110" pin lengths designate with the Suffix'-K', e.g. EXQ125-48S3V3-KJ. If the product is already a '-R' suffix product then the suffix will be '-RKJ' e.g EXQ12548S3V3-RKJ. CAUTION: Hazardous internal voltages and high temperatures. Ensure that unit is accessible only to trained personnel. The user must provide the recommended fusing in order to comply with safety approvals.
