Digital LED controller with two color mixing from Cirrus Logic for better color temperature quality

Cirrus Logic Inc has introduced its second family of digital LED controllers with digital TruDim dimmer compatibility technology. The new CS163X family provides two channel LED color mixing capabilities that allows LED bulb manufacturers to create warm and natural light quality.

The CS163X family enables improved color quality at up to 30 percent greater efficacy than with single channel white LEDs. The CS163X incorporates powerline calibration technology that allows manufacturers to calibrate bulb characteristics and to utilize LEDs with a wider variation in performance characteristics.

"Cirrus Logic's roadmap of digital LED controllers is helping LED retrofit lamp manufacturers accelerate consumer adoption by solving critical challenges such as dimmer compatibility and color quality," said Will Draper, strategic marketing manager for LED lighting products. "The CS163X family builds upon the near-perfect dimmer compatibility of our first family of digital LED drivers, the CS161X family, by adding two-channel color mixing technology to create improved light quality with up to 30 percent more energy savings compared to single-channel white LED bulbs. Having established performance benchmarks in both dimming and color quality, future generation products will focus on lowering system costs while maintaining this performance leadership."

LED retrofit bulbs are considered by many as the heir apparent to incandescent and compact fluorescent lamps, due to their superior energy efficiency and long life.

The CS161X is available in a 16-pin SOIC package and is priced at $1.06 (USD) in quantities of 100,000.
