The MST1163TQ is a LED driver TO-252 RoHS manufactured by MST which is designed to provide a constant current, while allowing for the direct drive of LEDs from an AC or DC power source. The MST1163TQ provides simple and efficient multi-level control of LED brightness, making it ideal for commercial lighting applications. It includes an adjustable current limit for the sustenance of LED life and current regulation across the range of LED voltages. Features of the MST1163TQ include a build-in temperature sensing and output transistor protection for under-voltage, over-voltage, and short circuit conditions. The MST1163TQ is also RoHS compliant and suitable for a wide range of operating temperatures.
