　　cypress公司的S6AL211是智能4路LED照明驱动解决方案,具有调光和调色等控制功能和集成了3V LDO稳压器.输入电压DC 24V,最大指标35V,输出功率72W,效率大于94%,主要用在商业照明,住宅区照明和其它照明.本文介绍了S6AL211主要特性,框图,商业照明系统DALI框图和应用框图,以及评估板特性,连接框图,电路图,材料清单和PCB设计图.

　　S6AL211 series provide an intelligent LED driver solution for commercial lighting, residential lighting, illumination lighting, and so on. There are possible to the light dimming and tune colors control of 4ch. LED strings. This device can be dimming and toning for 4ch. LEDs. The dimming and color control is corresponded to communication interfaces and sensors. Through it can use for not only the general lighting but also office, shop and residence lighting control systems. Moreover, S6AL211 series integrate a 3V-LDO regulator circuit for supplying the power to the peripheral circuits. It contributes to the BOM cost reduction. S6AL211 series can offer the best solution according to your usage.
