Cirrus Logic acquired more than 300 dimmers consisting of some of the most popularmodels on the market today and representing much of the global installed base. To test dimmer compatibility, Cirrus Logic developed a testing methodology that scores LED bulbs on multiple factors including:

• flicker-free operation (bulb does not flicker at any point along the full dimming range);
• smooth “monotonic” dimming (bulb dims steadily without sudden “jumps” or drops in light level); and
• full dimming range operation (bulb dims effectively from maximum to very low light output).

Cirrus Logic LED drivers offers smooth, flicker-free dimming across a wide variety of dimmers and also consistently outperform competing LED drivers in dimming range. Cirrus Logic’s ICs dim to nearly zero light output, which closely matches the dimming performance of incandescent light bulbs. Competing LED drivers are not capable of this level of deep dimming.
