100W DC/DC Converter Can Go As Low As 1.08V

A new half-brick, 100W dc/dc converter module is said to be ideal for powering products employing the latest low-voltage semiconductors. Available with single 5.0V, 3.3V or 1.8V outputs, the EXB100 has a high-efficiency, synchronous rectifier design capable of delivering high output current without the need for a heatsink. The 5V model is rated at 20A, while the 3.3V and 1.8V models are rated at 30A. Each has a voltage trim facility with an exceptionally wide range, allowing the output to be adjusted between 60% and 110% of nominal value. This means the 1.8V model, for example, can be trimmed down to just 1.08V, yet still deliver its full 30A rated output at this voltage level. System designers can easily perform margin testing by varying the supply voltage. According to the company, applications with highly specific voltage requirements can now be powered by standard off-the-shelf dc/dc converters, whereas they would previously have demanded more expensive, customized power sources. The open-frame units are intended for through-hole PCB mounting, with an industry-standard half-brick footprint of 2.4" x 2.28". The EXB100 series converters are primarily intended for the networking, telecom and wireless markets, where small size, lower output voltages with higher currents, low profile and high efficiency are all key demands. Pricing is $83 each/1,000. ARTESYN TECHNOLOGIES, Eden Prairie, MN. (952) 392-6538.
