cypress公司的S6SAL211是智能LED驱动器解决方案,只用一颗芯片实现最大4通道的调光/调色控制的LED驱动IC, 标准输入电压VIN为24V, 输出功率为72W,效率94%以上,适用于一般照明/吸顶灯/灯饰灯的LED照明,主要用在一般/办公/街头LED照明,筒灯或吊灯等住宅用照明,各种LED感应灯和灯光装饰. 本文介绍了S6SAL211主要特性,框图和几种简化系统框图,DALI系统框图,以及S6SAL211A31SA2001和S6SAL211A31SA3001评估板主要特性,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.
