EXB250 Series

•

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 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 90% for the 3.3 V, 88% for the 2.5 V and 87% for the 1.8 V 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 (TÜV Rheinland)

and UL/cUL1950, the EXB250 reduces compliance costs and time to market.

All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
