Hello,
I'm trying to repair an industrial led lamp, it has 20 pcb with 9 leds and some of the leds have burnt out. I have the photo of the other board for reference but I can't find the right part for the sot25 housing, the marking is A63.VG .
Can anyone tell me what this marking means?
Here is the value measured on another working pcb :
Pin 1 = PWM ?
PIN 2 = GND
PIN 3 = 0.220v
PIN 4 = 24V
PIN 5 = 24V
Attached the picture of the parts needed for replacement
