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
