EXB30 Series
Single output
DC-DC CONVERTERS 16-30 W High Efficiency DC-DC Converters
High efficiency topology, 92% typical at 5 V
Industry standard footprint
Wide operating temperature, -40 ˚C to +85 ˚C
(natural convection)
80% to 110% output trim
No minimum load
Overvoltage and overtemperature protection
Remote sense compensation
Remote ON/OFF
Available RoHS compliant
The EXB30 is a new high efficiency open frame isolated 30 Watt converter series in an
industry standard footprint. The first five models in the series feature a 2:1 input voltage
range of 36 Vdc to 75 Vdc and are available in output voltages of 12 V, 5 V, 3.3 V, 2.5 V
and 2 V. Each model is trimmable from 80% to 110% except the 12 V output which has
a wider trim range of 60% to 110%. The sub 5 V models have an output current rating
of 8 A. Typical efficiencies for the models are 92% for the 5 V, 90% for the 3.3 V and
12 V, 87% for the 2.5 V and 86% for the 2 V version. The EXB30 series offers remote
ON/OFF and remote sense compensation to correct for voltage drops at the load.
Overcurrent, overvoltage and overtemperature protection features are included as
standard. With full international safety approval including EN60950 and cUL1950, the
EXB30 reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
