Hello Everyone,
I as hoping someone might be able to identify and find a supplier for a component on the motherboard of my 3d printer.
The printer is an older Qiditech Tech 1 (Flashforge Creator Pro clone). The component failed during a pre-heating cycle. I heard a pop,
then smelled the burning of the component. The boards for this model are hard to find, so I was hoping to repair it.
The chip, I believe, is part of the 24v input circuit based on it's location. (IC 1, the empty space behind the 100uF cap in attachment 1)
A Google search of the part number yielded no apparent matches. Maybe an obsolete part? If so is there a substitute?
Any help in this matter would be greatly appreciated. Thank You.

Looks like this: L5970D

I think it is a L5970D from STMicrolectronics

Yep. You guys are absolutely correct.
Don't know why my search didn't come up with that. Maybe I transposed a number . Anyways, you guys are awesome. Thanks for the quick response. I just hope the damage didn't go any further than that particular component. I'll let you know how it works out.
