Just as a matter of personal interest, can you read the numbers off the 16 pin IC?
It has no numbers or other codes at all! It's solid black with a sort of fine stippled finish.

Take another look. I can see 4 rows of text but the resolution on the picture isn't good enough to make it out. FWIW, it's the square device in your second picture with 4 solder joints on each side, next to the octagonal device with "220" written on it (that's a 220uH inductor, likely part of a PWM or PS switcher circuit).

Sorry, Zen, it absolutely has no writing on it. I don't know if I can manage a micro photograph to convince you, but I'm using a high powered loupe in sunlight. It's just a stippled black finish.

4 lines of text. I think I can make out 4x35x on the first line, but that's it.
Those are reflections. There is no text, no letters, no numbers. I'll try to get a super-closeup photo later, but this is silly.
Here are two more shots, through a loupe:
