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.

CS1615属于集成电路（IC） > LED 驱动器。凌云逻辑制造生产的CS1615LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
