Need help on identifying an IC & finding its datasheet (probably Sanken made?)

[dav]

It's a SOP-8 PWM controller.
Its surface is a bit erased, I can read:

SC621
SK30

or something like this.
Any suggestions?

Could be this..a Sanken
    LED Light Management Unit Charge Pump,4 LEDs, 400mA Flash LED, Dual LDOs, and SemWireTM Interface

Thanks for reply.
Mmm... strange, my device is a power supply

Wait,
the motherboard is Sanken branded! (it's the official power supply of a Sony TV/Monitor).
Maybe this PWM controller is used on power supply, too

I cannot find its datasheet, neither on official website (Sanken SC6210).
Just tried on jotrin, but after login it redirects on sanken website and nothing...

Any help would be appreciated.

Reverse-engineer the schematic a little bit and find its pinout. It might be FAN6210, A6210, or some similar rebranded IC.

It might also be SSC6210:
http://www.sanken-ele.co.jp/en/news/contents/20070327_2e.htm

which could be related to SSC620D series: http://www.datasheet4u.com/download_new.php?id=822986

Reversed a bit the schematic, it's different from all of them.

Here the pinout:

1  Vcc
2  Feedback
3  GND
4  maybe Over Temperature Protection (*)
5  Startup voltage
6  NC
7  Gate Output
8  100R to GND and a capacitor to GND

(*) there is a path to a grey SMD component, with TH2 label, near the switching Mosfet. I measured 560R across it.

It seems there is not a Current Sense function, as the Source is at GND.
