Suited for ac/dc offline nonisolated applications requiring multiple LED circuits or requiring dc/dc color-mixing capabilities, the IRS2540xPbF and IRS2541xPbF series high-frequency buck regulator ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...

No matter how hard engineers try to prevent it, parts fail. LEDs are no exception, and with the cost and reliability expectations of LED lighting solutions, avoiding system downtime from shorts or ...

When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...

LED driver designs can deliver flicker-free and fast startup dimming performance while still providing high power factor and efficiency, writes Rich Miron Dimming performance of LED lamps in legacy ...
