If there is one thing I have learned in my years on this planet, it would be that it is human nature to staunchly choose sides. Whether it is Republican or Democrat, Coke or Pepsi, or Mac or PC, people love to rally behind the products they love and disparage the ones they don’t. In …
Introduction This application note details a step-by-step design process for the MAX16833 high-voltage high-brightness LED driver to speed up prototyping and increase the chance for first-pass success. The MAX16833 is a peak current-mode-controlled LED driver, capable of driving an LED string in several different architectures: boost, buck-boost, SEPIC, fly back, and high-side buck topologies. The …

DIN Rail-mounted relay interface module Finder Master Plus 39.3x integrates function of a switching and protective element into one component. Finder Master Plus was in detail described to you in our article Relay interface module with a fuse module. Thanks to a growing …
Whether for driving white LED backlights or powering RF and analog circuits, laptops, tablets and other mobile devices often require voltages that are much higher than the input supply voltage. Consequently, step-up or boost DC/DC converters generate output voltages that are several times the input to serve a variety of circuits and functions in these …
