New DCMs Bring High Power Density without Increasing Design Complexity

New DCMs Bring High Power Density without Increasing Design Complexity

One of the most common challenges for electronics design engineers is the need for power density. Hybrid electric vehicles, for example, are one of the many applications that must deliver high levels of power, yet optimizing the use of space is one of the critical design goals.

The Next Generation of Bricks Launches Today

The Next Generation of Bricks Launches Today

The brick DC-DC converter is a form-factor that has become incredibly popular with power system designers since we introduced the industry’s first full-brick in 1984. They are reliable, robust and easy-to-use, with an integrated baseplate that significantly simplifies cooling, no requirement to mount on a PCB and integrated peripheral components. Continual innovation has improved the internal electronics, enabling increases in performance within the same footprint.

Back to Basics: Using Remote Sensing to Ensure Accurate Point of Load Voltage Control

Back to Basics: Using Remote Sensing to Ensure Accurate Point of Load Voltage Control

Today’s ASICs and processors typically operate on a low voltage and therefore require high current. This means that if they are placed at any distance from the power supply or DC-DC converter that feeds them, transmission losses can become an issue. Because of resistance and therefore voltage drop in the power path between the converter and load, the voltage across the load will be lower than that across the converter’s output terminals. The difference is given by I x R,

Technical Paper: Bi-Directional DC-DC Converter

Many systems require battery banks to provide a backup should the main power source fail. At APEC 2014, Xiaoyan (Lucy) Yu presented a paper that she co-authored with Paul Yeaman describing a bi-directional converter suitable for such applications. A bi-directional topology simplifies the design of the power system that must charge the battery and also draw power from them when the main supply fails. The converter described was able to deliver excellent performance, supplying 300 W when charging the battery and 1500 W when supplying power to the DC bus. This was achieved with...
