Part Number: TPS54040 Hi,
I'm trying to use TPS54040 as an inverting buck boost converter, and with the part values that I have calculated from the spreadsheet tool, I haven't got any results that make sense with the simulation tools provided.
I was…
Part Number: TPS54040 Hi team,
I've found the following PCN stating the change of thermal pad area. Could anyone let me know if this change requires the customer to change their design accordingly?
Is there any guidelines or collaterals for this change…
Part Number: TPS54040 I would like to know if it is normal to find either Texas Logo or "TI" on the top of the marking (even in recent datacodes). (See pictures attached).
If both of them are Original, why is the difference? Different COO or DateCode…

My customer is facing shortage for TPS57040-Q1, and find that should be P2P compatible between TPS57040-Q1 and TPS54040. Currently, we are making detailed comparison between…
Part Number: TPS54040 Other Parts Discussed in Thread: TPS560430 Hello,
I would like to create a simulation model of TPS54040 for SIMPLIS.
For this I need to know:
What is the value of the internal slope compensation?
What is the value of the…
Part Number: TPS54040 Hi Team,
TPS54040 has only one HVSSOP (DGQ) package but have two version of thermal pad on P48 and P51 datasheet. And I can only find P48 thermal pad info on TPS54040A device with the same DGQ package. Could you please help confirm…
