Looks like I let my creative thinking run away too much!

Isn't this a linear regulator ?

Hi, your chip looks very similar to chinese SF6761S http://www.sifirsttech.com/admin/datasheet/SF6761S_DS_final_v1.0.pdf
However, if your diagram is drawn right: 1). You must solder this chip upside down 2) This chip has positive current sense voltage. Must say, I've never seen modern pwm chips with negative CS, so it looks really very strange to me... Maybe you can post photos of your PCB so we can see this wonder?...

I was looking for chip with similar markings and found this:
