There are possible to the light dimming and tune colors control of 4 ch. LED strings. This device can be dimming and toning for 4 ch.LEDs. The dimming and color control is corresponded to communication interfaces and sensors. Through it can use for not only thegeneral lighting but also office, shop and residence lighting control systems. Moreover, S6AL211 series integrate a 3V-LDO regulatorcircuit for supplying the power to the peripheral circuits. It contributes to the BOM cost reduction. S6AL211 series can offer the bestsolution according to your usage.
