Switching waveforms produced by modern point-of-load regulators (POLs) feature rise times in the vicinity of 1 nanosecond. As new gallium nitride transistors make their way into these regulator designs, we can expect that these switching speeds will get even faster. If so, will you be ready to measure them? Steve Sandler tackles this issue and others relating to switch-node measurements in his latest video on Troubleshooting Distributed Power Systems. Besides discussing requirements for time and frequency domain measurements of switching waveforms, he explains why certain measurements are important and the implications for power supply stability and noise performance. This issue also touches on POL design in Tim Hegarty’s article on inductor DCR current sensing. This article introduces a new technique for improving the accuracy of this lossless current sensing method, which has been implemented in a new PWM controller from TI. Another feature by Martin Kanner demystifies the selection of copper wire for interconnects and magnetics design, while enlightening us about the subtleties of the copper wire table. Also in this issue, an article exploring the unique issues encountered in the design of high-voltage power supplies, the unveiling of How2Power’s new section on silicon carbide and gallium nitride technology, new power products, and more.
