MP6517A/B difference

What is the difference between MP6517A and MP6517B?
MP6517 ( null) has lower operating input voltage and lower current, but I did not find
the difference between MP6517A and B.

Best Regards

Hi kanji_shibatani,

Thank you for contacting MPS. The MP6517A/B are very similar devices, I will check with my product engineers for the differences as the datasheets for the devices are nearly the same.

Update: I am told that there is no longer a difference for the current versions of the MP6517A and MP6517B. They are the same part as of today.
