Overview

The CS1615 and CS1616 are high-performance single stage dimmable offline AC/DC controllers. The CS1615/16 is a cost-effective solution that provides unmatched single and multi-lamp dimmer-compatibility performance for dimmable LED applications. The CS1615 is designed for 120VAC line voltage applications, and the CS1616 is designed for 230VAC line voltage applications.

Across a broad range of dimmers, the CS1615/16 provides smooth flicker free dimming, and consistently dims to nearly zero light output, which closely matches the dimming performance of incandescent light bulbs. Cirrus Logic¡¯s patent pending approach to dimmer compatibility provides full functionality on a wide range of dimmers, including leading-edge, trailing-edge, and digital dimmers.
