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 to 75VDC and are
available in output voltages of 5V/3.3V and 3.3V/2.5V. 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 5V/3.3V and 90% for the 3.3V/2.5V 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, (TÜV
Rheinland) and UL/cUL1950, the EXQ60 reduces compliance costs and time to market.
