AbstractAn Efficient Power Driver For Color Light Emitting Diodes (Led) Is Disclosed For Driving Multiple Leds For Producing Different Desired Colors. Such Led Combinations Comprising Leds With Different Primary Colors Are Suitable For Implementing Pixels In Displaying A Digitized Image. This Disclosed Invention Provides Switching Power Conversion Embodiments Such That A Single Apparatus Drives Different Color Leds. Furthermore, The Disclosed Invention Provides Configurations With And Without Input To Output Isolation While Enabling Control Of The Current Through Each Led, For Instance By An Inductor Or Operating Condition.
