    SMD code marking help

    Hi, I will take your advise and desolder and measure one of those on Monday as I left the board at work... Regarding the rest, I agree that it's rather confusing. Not sure if it makes sense to be designed that way, but it came to my mind the unknown element might be a pnp device with internal...

    SMD code marking help

    Hi, The continuity was done on a functional ICs, in fact there was 4 in total I checked it on, which are driving each side of a RGBW led. On the question about what's connected before pin #1, there actually are 2x PUMH11 (dual npn package) with each branch driving one of the 4x ICs. And if we...

    SMD code marking help

    Thank you for your answers guys. The chip very much looks like some sort of a Npn device, but its connection in the circuit literally doesn't match anything I was able to find that matches this Smd code. I've drawn a simple schematic of how it appears to be connected. Any more suggestions are...

    SMD code marking help
