Well, I would have thought that a telephone call to the equipment manufacturer would be the quickest route to an answer, then I'm funny that way.

Where is the IC installed?

  • A printer?
  • A CNC mill?
  • A blender?
  • A remote control cat toy?
  • Why do you need to know
  • Who makes the PC board?
  • Etc. Etc. Etc.

That's 8 questions out of 20.
OP it's your turn!

There is no point in using an IC, the properties and characteristics of which are not understood, in any design!

Simply use a different IC, the properties and characteristics of which are given in a datasheet that is accessible.

If the Quest is to reverse-Engineer a product that contains an IC that is proprietary and the details of it are unknown, then any invitation to assist is declined on the basis of not wishing to be an accessory after the fact.

Thank you Rixter, this IC look like same as this IC but the mark indicated on the surface is N854 nor N292.

I could not found any info indicated the difference between these marks in the datasheet of this IC.

Does anyone can help !

Did you look at the data sheet for the Linear part LTC6102CDD?

It specifies part marking for some of the parts as just LCKH.

The other markings on the device are probably for factory of manufacture and date code.
