General Description

VAS1085 is a wide input range constant current LED driver to provide cost-effective solution for advertising light boxes, landscape lighting and other LED illumination application. For common application, VAS1085 needs only one external resistor to set the LED current. For high current application, several VAS1085 can be connected in parallel to deliver higher outputpower. VAS1085 can achieve 85% full setting currentwith only 1.35V input voltage, with this feature, it is ideal for applications with extremely low power supply voltage. Integrated over temperature protection, the LED current will 

automatically reduce when the die temperature reaches 140°C, and shut down when the die temperature reaches 160°C.
