The EXQ60 is a new high efficiency, open frame, isolated 60 Watt converter series in an industry
standard quarter-brick footprint. The EXQ60 delivers very high output current at low voltages, and
excellent useable power density for today's high end applications. The first two models in the series
feature an input voltage range of 33 V to 75 V and are available in output voltages of 5/3.3 V and
3.3/2.5 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 5/3.3 V and 90% for the 3.3/2.5 V version. The
EXQ60 series also has a remote on/off capability. Overcurrent and overvoltage protection features are
included as standard. With full international safety approval including EN60950, (TV Rheinland) and
UL/cUL1950, the EXQ60 reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
