This design example report is a 15 W low THD, high efficiency, universal input LED driver using LYTSwitch™-4 LYT4213E. This design operates with an input ranging from 95 VAC to 265 VAC and produces an ...

This design example report discusses the 5 W universal input, CV/CC isolated flyback LED driver employing LYTSwitch™-2 LYT2002D. This design operates at an input voltage ranging from 90 VAC to 265 VAC ...

The HV9961, an average-mode, constant-control LED driver IC designed to drive LEDs using a buck topology, is well-suited for a variety of solid-state lighting applications. The HV9961 provides current ...

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 ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...
