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.

Applications

• Retro-fit LED Lamps

• External LED Drivers

• LED Luminaries

• Commercial Lighting
