We lost the great analog guru Jim Williams last June. But before he died, he finished one more work, a beautiful 932-page book called Analog Circuit Design: A Tutorial Guide to Applications and Solutions, that’s perfect for any engineer’s coffee table.

Surface arcing or arc-over discharge across MLCC terminals is a major problem in high-voltage design, particularly in automotive apps at 500 V and higher. KEMET’s ArcShield devices, though, inhibit surface arc-over discharge and prevent damage to the capacitor and surrounding components on a PCB.

The buck-boost dc-dc switching converter (one that provides a constant output voltage regardless of whether the unregulated input voltage is greater than or less than Vout) presents a greater design challenge than a simple buck or boost. Of the various circuit topologies available, the H-bridge presents the most attractive solution. This Basics of Design derives the H-bridge from its classic roots, explains the differences among alternative topologies, and describes the optimum implementation of the H-bridge buck-boost.
