Coilcraft has provided models of their XAL family of power inductors in the SystemVision Partner Library. This article shows the importance of the "soft saturation" magnetic characteristic of these parts, which can prevent catastrophic transient over-currents during start-up and other operating conditions.

In vehicles with a “Start-Stop” operating mode, the engine is turned off frequently to improve fuel economy. But low-voltage drop-outs must be avoided during re-start. The NCV8876 from On Semiconductor makes it easy to boost the voltage during these drop-out events. This article shows you how!
