The EXB30 is a new high efciency open frame isolated 30 Watt
converter series in an industry standard footprint. The rst ve
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
efciencies for the models are 92% for the 5 V, 90% for the 3.3 V
and 12V, 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.
