(I post here instead of Automotive forum, because it's now in read only.)

Hi,

I have a customer who has used TPS43331-Q1 for their project. It seems the datasheet has been update as below.
Can you help me to address questions from customer below convince customer accepting this datasheet changes?

<Q1>: From Original to Revision. A, removing minimun output current of Ch1

What is the background of this deletion?
The minimum output current could affect to the stability of DCDC's control loop.

<Q2: Voltage Tolerance of Vstby>:

Removed once, but brought back again. What was that?

I'm sorry to asked many old stuff...Thank you for your support.
Regards,
Ken

Hi Ken,

Unfortunately, the person who implemented the datasheet changes is out of office right now for the next couple weeks, so I don't know the exact reason these were implemented. However, we did find that these changes were made intentionally, so it looks like the latest datasheet is correct.

Regards,
Karl

Hello Ken,

sorry for the delay due to my absence...

The minimum current was removed on purpose, since it was misleading and customers inquired if they need to apply a minimum load. Ther eis no minimum load applicable.

The 8% output voltage tolerance at high VIN(SB) is correct and was accidentially dropped in the A-revision and thus added back in the B-revision.

I hope this aids your discussion with the customer, if not already done...

Best regards,

Frank

Hi Frank,

Wow, you kindly support such old post!
Thank you for your feedback!

So far no argument from my customer, so this can be closed.

Thanks,
Ken
