Power Supplies for LED Driving [Paperback]

Light-emitting diodes are being widely used due to their efficient use of power. The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), and many more.

Powering (driving) these LED's is not always simple. Linear driving is inefficient and generates far too much heat. With a switching supply, the main issues are EMI and efficiency, and of course cost. The problem is to get a design that meets legal requirements and is efficient, while costing the least. This book covers the design trade-offs involved in LED driving applications, from low-power to UB-LEDs and beyond.

* Practical, hands-on approach to power supply design for LED drivers
* Detailed examples of what works and why, throughout the design process
* Commentary on how the calculated component value compares with the actual value used, including a description of why the choice was madeIntroduction; Characteristics of LEDs; Driving LEDs; Linear Power supplies; Switching Power Supplies; Selecting electronic components for power supplies; Magnetic; EMI and EMC Issues; Thermal issues; Safety issues.
The essential guide to designing cost- and energy-efficient power systems for LED devices.Steve Winder is now a European Field Applications Engineer for Intersil Inc. Steve works alongside design engineers throughout Europe to design circuits using components made by Intersil Inc, a US based manufacturer of CMOS ICs used for power supply controllers and for analogue signal processing.

Prior to joining Intersil Inc., Steve worked for US based Supertex Inc. in 2002, where he was instrumental in encouraging Supertex's management to start developing LED drivers. One of Steve's German customers had started using a relay driver for LEDs and once Steve had explained the technical detailC\
