Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...
A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...
Editors’ Note: This segment is adapted from Chapter 2 of Power Supplies for LED Driving by Steve Winder. Since an LED behaves like a constant voltage load, it can be directly connected to a current ...
