Please ID this SMD part

I have a 6-pin SOT size chip marked as shown below.  I think it's a DC converter, but not sure which way.

Thanks for any clues.

Next time, to make it easier for you, take the readings and identify the package.

smd SOT-23-5 AMB
And take a look on Google pictures.

You mean sot23-6... and here's a datasheet but the only one I could find is in Chinese.

Thanks very much.  Yes, I think that's it.  I've confirmed the circuit, and it's indeed a boost converter.  And with the feedback voltage at 0.6V, the divider resistors 75K and 10K make perfect sense.

When purchasing from Aliexpress, it's advisable to buy a module for initial testing. Acquiring individual ICs from such marketplaces can be unpredictable. I concluded this after encountering several devices that were irreparable due to faulty components. I lost money on it.
Buy it from LCSC if you want a good Chinese seller.

Best wishes.
