We have found this to be the failing component of a multi voltage DC power supply. This little daughter board is going to prove very tricky to try and remove the coating to get at the components. The chip is undoubtedly proprietary. The OEM of the machine this goes in is out of business. The OE of the chip is in Japan and I can find no support at all for it.
I have been told it might be an op amp but I am really not sure as of yet.
Ideas? We need this thing running a week ago so I need to make a decision like now if we need a different power supply or if we can figure this chip out. There is one identical to it in the circuit that is most likely good as it is showing voltage outputs. This one does not. Not sure if we could compare the two but that might be a serious challenge.
