Abstract: For lighting application, high-power LED nowadays is driven at 350mA and a sensing resistor is used to provide feedback for LED-current regulation. This method adds an IR drop at the output ...

Part 2: A 60V buck-boost controller drives high power LEDs, charges batteries and regulates voltage with up to 98.5% efficiency at 100W and higher. Part 3: Offline LED lighting simplified: A high ...

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 ...

A novel integrated circuit for driving LED lighting has been proposed, designed and fabricated. Besides the typical parts of LED driver, an integral part was added at ...

The Cilgerran castle was originally intended to drive a bunch of higher power LED's. Driving small LED's is quite simple, but as we move to long LED strings and the 1 watt and 3 Watt "Star LED's", ...

Guest columnist Jeff Gruetter, product marketing engineer for power products at Linear Technology outlines why high brightness LEDs require high performance LED drivers High brightness (HB) white LEDs ...
