描述 Description

VAS1082 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, VAS1082 needs no external components. For high current application, several VAS1082 can be connected in parallel to deliver higher output power.

VAS1082 can achieve 85% full setting current with only 1.3V 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.VAS1082 is available with SOT-23 package
