DESCRIPTION

The EXB50-48D05-3V3 is a 50W independently regulated dual-output DC-DC converter designed for low-voltage silicon applications in networking, telecoms, and wireless markets. It features two positive outputs with 5V and 3.3V nominal voltages, each capable of delivering up to 7.5A, with a maximum total current of 15A and typical efficiency of 89%. The converter operates from a 36–75 Vdc input range with an industry-standard 1/2 brick open-frame package, offering ultra-wide output voltage trim range, no minimum load requirement on either output, and comprehensive protection including short-circuit, overvoltage (latching), and thermal protection with automatic recovery at 125°C. Operating over an ambient temperature range of -40°C to +70°C under natural convection, the unit is approved to IEC60950 and UL/cUL1950, complies with ETS 300 019-1-3/2-3 and ETS 300 386-1, and is available in RoHS-compliant versions, making it ideal for demanding applications requiring high efficiency, small size, and robust protection.
