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 ...

If you are looking to replace halogen bulbs with LEDs, combining a rectifier bridge and a current-controlled synchronous step-up/step-down converter creates a high power factor driver circuit, writes ...

The advent of high-power LEDs that can replace incandescent bulbs has produced a need for circuits that efficiently match the LEDs to available power sources (batteries, car electrical systems, etc.).

Opto-electronic systems frequently require temperature stabilization for components such as laser diodes, photodiodes, prisms, and lenses. The established method for providing stabilization is to ...

In this article, I would like to talk a little bit about LEDs, including why they will become the lighting source of choice, how to power them and also, how to protect them from the hazards they face ...
