Strange unknown part!

[Antwan]

High guys I picked up a batch of lighting online cheap ic managed to do alot of the repairs but the last bits are all the led drivers all seam to gave the same issue on the green led side of one of the 4 units

Iv chased it down to the below part any ideas i assume it a dual mosfet of sorts as it seams to receive a pwm signal from the cpu and it puts out to 2 different sections of the led cluster but seams it fails on just half as the other side is fine .
hope someone can help

Could be a 3.3 volt regulator.
