Unknown SMD part

Good morning.

Recently I have been investigating a PCB, and there's one interesting SMD component. It is in SOT23-5 and it says "OKGM", but there's a horisontal line above the K, like the sign for "inverse"

It should be a step-up converter but it's not listed in the SMD codebook so I can't find it's real part name to get a datasheet.

There's no manufacturer logo.

If you have any idea about manufacturer, part number, etc, please post.

Hi
Just a thought,could it be UK.....GM(GENERAL MOTORS),whats it for?

Well we know it is not a Transistor because Q7 is a transistor
It has 5 pins so it could be a dual transistor or IC
It is marked on the board U11 that is a clue that it is probably an IC
If we knew what it came out of with a model number we could maybe find a schematic

The package could be any of these:
SC-74A (mini mold)
SOT-23-5
SC-88A (SSP)

Based on the diode, inductor and transistor there I would agree it seems to be a DC/DC converter most likely. Looks like an SOT-23-5 to me. Have no idea on the part number, sorry.
