EXB50 Dual Series Dual positive output DC-DC CONVERTERS 50 W High Efficiency DC-DC Converters • Two independently regulated positive outputs • Each output offers ultra-wide output voltage trim range • High efficiency topology, 89% typical • Approved to IEC60950, UL/cUL1950 • Operating ambient temperature of -40 °C to +70 °C natural convection • No minimum load on either output • Complies with ETS 300 019-1-3/2-3 and ETS 300 386-1 • Available RoHS compliant 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 1/2 brick footprint, the EXB50 Dual can deliver up to A from either 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 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.
