Abstract
In today’s lighting industry, there is a high demand for quality, long-lasting light bulbs. Light emitting diodes offer the means for long-life bulbs, while producing a quality output. The issue with the current state of solid-state lighting is how to drive LEDs and maintain their full potential. Many solutions offer either a long-life bulb or a high quality output. The trade-off for a long-lasting bulb typically comes with an output quality that is visibly or invisibly flickering. In order to effectively eliminate flicker from the output of the LED, a large output capacitor is needed. An electrolytic capacitor is a desirable choice because its capacitance can be quite large, while maintaining small package size. The drawback to electrolytic capacitors is their limited lifespan. By eliminating the limiting factor, the electrolytic output capacitor, from the driver, the LED can perform to its full potential lifetime. With the addition of a buck-boost topology in place of the electrolytic output capacitor, the flicker in the LED can be effectively eliminated, while maintaining a small package size. The result is a long-lasting, quality output LED driver.
