TPS62745: MSL of TPS62745DSSR

Gk110

Part Number: TPS62745

Hi Team

I’d like to ask about MSL of TPS62745DSSR.

This time, MSL1 and MSL2 products were delivered to our customer.

We confirmed that the latest data sheet has an MSL of 1.

However, there was no history of a PCN being issued.

When did MSL change?
Will a PCN be issued?

Best regards,

Hello Sir,

How can you get information of MSL level changed?

Could you provide related qualification to us for check?

Thanks

Hi Colin-san

I have obtained an image that shows the difference in MSL.

When did MSL change?
Will a PCN be issued?

Best regards,

Hi Sir,

PCN is only required for any MSL downgrade per QSS009-043. MSL 2 to MSL1 is an improvement on the floor life after the bag is opened from 1 year to unlimited per J-STD-020E. MSL upgrade has been taking place for years and has never resulted in a PCN.
MSL change happened around Sep/2023 timeframe.

Thanks

Colin
