　　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.
