Yes, per page 2 of the D/S, the BYN identifies the device and this matches the TPS62290. The other markings are for tracing the date code, lot, etc.

Thanks for the answer.

But I want know what date code and lor etc. it is.

This means I want know what combination of alphabetic character represents the date.

On this device and many others, the first two digits are the year month designation. So, 1C is 2011 December.
