A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

Here is a look back of Allegro’s A8515, a wide input voltage range, high efficiency fault tolerant white LED driver. The device was made available in the market since 2010. It features multiple output ...

LED lighting, or solid-state lighting (SSL) offers advantages in energy consumption and feature capabilities over conventional lighting sources, but requires careful attention to the capabilities and ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...
