About Power Supplies For LED Driving
About the Author 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 detail of this application to Supertex’s management, they decided to start an applications team to develop LED specific products. Supertex then invested heavily to became a leader in this field. Microchip acquired Supertex in 2014.Until 2002, Steve was for many years a team leader at British Telecom Research Laboratories, based at Martlesham Heath, Ipswich in the UK. Here he designed analog circuits for wideband transmission systems, mostly high frequency, and designed many active and passive filters.Steve has studied electronics and related topics since 1973, receiving an Ordinary National Certificate (ONC) in 1975 and Higher National Certificate (HNC) in 1977 with Endorsements in 1978. He studied Mathematics and Physics part time with the Open University for 10 years, receiving a Bachelor of Arts Degree with 1st Class Honours in 1989. He received a Master’s Degree in 1991, in Telecommunications and Information Systems after studying at Essex University. Since 1991, he has continued with self-study of electronics, to keep up-to-date with new innovations and developments. Product Description Power Supplies for LED Driving, Second Edition explores the wide use of light-emitting diodes due to their efficient use of power. The applications for power LEDs include traffic lights, street lamps, automotive lighting, architectural lights, theatre lighting, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), LCD display backlighting, 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, efficiency, and of course cost. This book covers the design trade-offs involved in LED driving applications, from low-power, to UB-LEDs and beyond. Review The essential guide to designing cost- and energy-efficient power systems for LED devices From the Back Cover The essential guide to designing cost- and energy-efficient power systems for LED devicesPower Supplies for LED Driving covers almost all the applications for power Light-emitting diodes (LEDs) including traffic lights, street lamps, automotive lighting, architectural lights, theatre lighting, household light replacements, signage lighting (replacing neon strip lights and fluorescent tubes), LCD display backlighting, and many more.This book covers the design trade-offs involved in LED driving applications, from low-power to Ultra-Bright LEDs and beyond, and to equip engineers to get a design that meets legal requirements and is not only efficient, but also cost-effective.Power Supplies for LED Driving enables electronic engineers and circuit designer to learn the limitations and compromises of LED Driver systems design; choose the best topology for an application, whether it be linear, buck, boost or another type; understand the differences in driver ICs from different suppliers; mitigate the effect of parasitic components; and learn how the specification of an application can define the type of LED driver circuit and control system used.
