I have to repair couples of LED lamps with integrated led driver with constant current.
but label of IC is looks like OEM but could it be your products:
AZTAWA, AZTAXA, ARJBCA they are in SOIC-8 case
if Yes then could you be kind to give me link for datasheet of those LED drivers. Or even pin description
Welcome to the MPS Technical Forum. I can verify that these SOIC-8 devices are not from MPS. Would you be able to share the system specs for the LED lamps please?
input voltage is +48V
current is 350mA-700mA depending of Rs
Please check out our MP2487 IC. Datasheet is available on our website
thank you will try to replace it.
Any idea (see schema of my PCB) of pin descrition? https://c2n.me/4aNwpo3
I am not sure if replacing an unknown part and a non-MPS with the MP2487 is a good idea. We strongly suggest not to do the replacement. I have suggested the part for your future designs and not for replacement.
