60V 2MHz Buck-Boost Controllers Regulate High Power Voltage and Current with High Efficiency and Low EMI

Keith Szolusha - Applications Engineering Section Leader Aug 24th 2017
Design Note DN567: Introduction Synchronous buck-boost controllers are versatile and highly efficient. They can produce high power as both a boost and a buck with a single inductor, keeping power supply design simple. Normally, a buck-boost controller in a high power application is operated at a standard or low switching frequency, ...

Meet Green Standards in 24VAC and 12VAC Lighting Systems: Replace Halogen Bulbs with LEDs Driven by High Power Factor, High Efficiency Converter

Keith Szolusha - Applications Engineering Section Leader Oct 17th 2013
LEDs are increasingly used in 24VAC and 12VAC lighting systems as a robust, energy efficient and high performance alternative to halogen lamps. Power converters that drive the LEDs should have a high power factor (above 90% in order to meet generally accepted green standards), should be efficient, use a minimal number of components ...

60V, Synchronous Step-Down High Current LED Driver

Walker Bai - Applications Enginneer Nov 1st 2012
Introduction The meaning of the term “high power LED” is rapidly evolving. Although a 350mA LED could easily earn the stamp of “high power” a few years ago, it could not hold a candle to the 20A LED or the 40A laser diodes of today. High power LEDs are now used in DLP projectors, surgical equipment, ...
