TPS5420: The bottom side markings are different in the same reel

Johnny Wong

Part Number: TPS5420

Hello,

we found the bottom side markings of TPS5420DR in the same reel(adjacent parts) are totally different, why does such thing exist? didn't they come from the same production line and should be with the same bottom side marking?

Hello Johnny,

If you are ordering from TI approved vendor then devices are genuine, if not, TI cannot guarantee they are.

Hello Johnny,

I am unable to provide further support, per company policy.

I will need to close out this thread.

Would urge you to source product only from approved TI vendors to ensure it is genuine.
