Overview

The CS1615A and CS1616A are high-performance single

stage dimmable offline AC/DC controllers. The

CS1615A/16A requires fewer off-chip components than

the CS1615/16 resulting in a lower total BOM cost. The

CS1615A/16A provides unmatched single- and multi-lamp

dimmer-compatibility performance for dimmable LED

applications. The CS1615A is designed for 120VAC line

voltage applications, and the CS1616A is designed for

230VAC line voltage applications.

Across a broad range of dimmers, the CS1615A/16A

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 Luminaires

• Commercial Lighting
