CS1615/16

Single-Stage Single-Channel Dimmable LED Control

The CS1615/16 are single-stage LED drivers that provide industry-leading dimmer compatibility, enabling LED lamps to match the dimming experience of incandescent lamps. Cirrus Logic's proprietary digital intelligence allows the CS1615/16 to monitor and adapt to the type of dimmer in use and select the appropriate operating mode. This adaptive digital signal processing technology, which is not possible with competitive analog drivers, ensures a smooth, flicker-free dimming performance across a zero to 100 percent dimming range.

The CS1615/16 are configurable for isolated and non-isolated topologies and have a BOM cost equal to competitive single-stage solutions.
