Intersil’s ISL8117 is the first 60V sync buck controller able to bypass the intermediate step-down conversion stage traditionally employed in industrial applications. The controller’s low duty cycle enables the direct step-down conversion from 48V to a 1V POL, making it possible for you to reduce system complexity and solution cost in a variety of applications. […]

If you’ve poked around the internets where electronics hobbyists collect, it is likely that you are acutely aware of our incontrovertible affinity for building timekeeping clocks. It is similarly unlikely that you have been able to evade the plenitude of nixie tube based projects. There is a reason for this. Nixie tubes are cool. They
USB data-acquisition modules offer good value and ease of use. Which makes them an attractive choice for manufacturing test. But before you use the modules in a manufacturing test system. You need to take steps to protect them. During manufacturing test of circuit boards or subassemblies, a defect in an assembly may result in a

The Chebyshev filter features a steep roll-off, but has ripple in the pass band. So it is not suited for audio signal use, where a flat response is ideal. The roll off is so fast that the common definition for cut-off frequency does not work for Chebyshev filters. For this type of filter the cutoff
