Power Supplies for LED Driving 1st Edition

by Steve Winder (Author)
3.8 out of 5 stars 8 ratings
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 made

The essential guide to designing cost- and energy-efficient power systems for LED devices.

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.

    5.0 out of 5 stars Very Practical
    Reviewed in the United States on November 23, 2011
    Format: PaperbackVerified Purchase
    I've got most of the other major switch mode power supply books, but this one is much more practical. The book can be used for general power supply design as well, but it tends to focus on the lower output power range of LEDs. You see a definite Supertex bias to the examples since the author is connected with that company, but it doesn't read like an application note.

    4.0 out of 5 stars Useful - no nonsense book
    Reviewed in the United States on January 9, 2013
    Format: PaperbackVerified Purchase
    This book does a great job of presenting several different LED power supply solutions with explanations of their pros and cons. It goes into depth and detail with enough explanation to help anyone with a reasonable technical background. If you are not an electrical engineer, the circuits are generally simple enough to handle if you take your time and read carefully. I would have given it five stars but I saw places where the text could have been a bit more in depth. It won't lose you if you are willing to read certain passages more than once.

    Just to mention, the circuits favor one brand of IC manufacturer - not a big deal, and maybe a good thing if it gave the author a way to make the circuits ready for readers to breadboard. Sometimes generic circuit designs with generic IC's are painfully too abstract. They typically leave you wondering what to do with extra IC pins with a real world chip. Not a big deal if you are an engineer, but a big deal when you are treading into new vistas of knowledge. I am an engineer, but I really enjoy seeing ready to go circuit designs like in this book. I can breadboard a circuit like the ones in this book - and do it without a great deal of time invested. Then, if I decide to use some other manufacturer's IC in the long run, I can worry about any IC differences at that time. If the author favors a certain IC manufacturer, so be it -- not a problem for me.

    2.0 out of 5 stars Not worth the time for me :(
    Reviewed in the United States on August 31, 2016

    This is just an intro collection of reference schematics without any useful explanation. Mostly design specific and thus very little to learn. Better off reading some datasheet and design guide. Also, slightly outdated in my opinion.

    Not for beginners. But for advanced hobbiest and possibly pros: lotsa math and formulae conveniently associated with specific circuits.

    The Author Steve winder is a Field applications Engineer who works for Supertex Semiconductors has written the book to cover Supertex products well. I would have given it 5 starts if it was covering wide range of product brands. In spite of the somewhat biased view. I still think it is worth a read to any engineer who is working with LED drivers.

    Good written and the explanations are clear. But knowledges about switching power supplies are needed previously, since in those chapters the book is oriented to the application of those schemes to LEDs
