This article is excerpted from Section 21 of “Analog Circuit Design: Volume 3 – The Design Note Collection,” (ISBN: 978-0-12-800001-4), edited by Bob Dobkin and John Hamburger of Linear Technology ...

International Rectifier, IR®, a world leader in power management technology, introduced the IRS2980 high-voltage buck regulator control IC for LED light bulb replacement, LED tube lighting and other ...

High-brightness LEDs are an inexpensive, robust, and green replacement for halogen light bulbs. This Idea for Design shows you how to apply an AC LED driver to convert the usual 12 or 24 V AC ...

Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...

The deployment of electronic LED lighting has grown dramatically over the past five years. Most luminaire manufacturers now offer a family of high-bay industrial LED products operating at AC line ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a leading global innovator of LED products and technology, announced that it has introduced high-power LED package ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

A newly developed white organic light-emitting diode operates at under 1.5 volts, report researchers from the Institute of Science Tokyo. By using triplet–triplet annihilation to generate blue light ...
