Top marking of MP6600

Top marking of MP6600 is given as MP6600 in datasheet but the IC i received from element14 has marking M6600L.
Is the part genuine?
Or I have received some duplicate part?

Hello Design,
There is a part MP6600L with that topmark. Please check the ordering information, the package marking to make sure the part is supposed to be the MP6600. If the MP6600 was really supposed to be shipped, contact Element14 about this shipment and request replacement if available.
