EXB50 Dual Series

•

The EXB50 Dual is a 50W independently regulated dual output dc-dc converter specifically

designed to meet the power needs of low voltage silicon. Housed in an open-frame package

with an industry standard

output, and up to 11 A in total, at temperatures of up to 70 ºC under natural convection. With

some forced air and/or reduced ambient temperatures, the EXB50 can deliver up to 8.5 A from

either output, and up to 17 A in total. The converter is primarily intended for the networking,

telecoms and wireless markets, where small size, lower output voltages with higher currents,

low profile and high efficiency are all key demands. Product features include wide output trim

and remote on/off. Overvoltage, short circuit and overtemperature protection combines to make

the EXB50 Dual a very robust and flexible product.
