DC DC converter

An isolated DC-DC converter can be built from a transformer, a controller, and a handful of discrete parts—or bought as a module that packages all of it into one component. For gate-drive supplies, industrial control boards, and sensor power, the module is often the engineering-correct choice: it moves the isolation design, the magnetics, and the … Read more

Two letters on a datasheet—”trench” or “planar”—tell you more about a power MOSFET than most of its front-page numbers. The structure determines how the device achieves its on-resistance, how fast it switches, how much gate charge it needs, and where it will and will not be cost-effective. This article compares the two technologies at the … Read more
