EXB250 SERIES
Single output
High efficiency topology, 90% typical at 3.3V
Industry standard footprint
Wide baseplate temperature, -40C to +100C
(natural convection)
90% to 110% output trim
No minimum load
Overvoltage protection
Remote on/off
The EXB250 is a new high efficiency, open frame, isolated 165 Watt converter
series in an industry standard half-brick footprint. The EXB250 delivers very high
output current at low voltages, and excellent useable power density for today's
high end applications. The design takes advantage of open frame construction to
provide a low weight, low thermal impedance baseplate design. 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.
Typical efficiencies for the models are 90% for the 3.3V, 88% for the 2.5V and 87%
for the 1.8V version. The EXB250 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 EXB250 reduces compliance costs and time to market.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
