Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Other Parts Discussed in Thread: TPS54294 , TPS54494 We used the TPS54294 part in the RTM proto board and power supply design is proved.
As per the new current requirements planned to use the TPS54294 in the proto-2 design.
We observed the following difference…
Other Parts Discussed in Thread: TPS54294 Hi ,
I have designed TPS54294 DC/DC convertor. It is not working, my circuit is below. We have not mounted R72 between SGND and PGND. Please help me to solve the issues.
Thanks and Regards,

Other Parts Discussed in Thread: TPS54294 , SWITCHERPRO , TPS54291 Hello,
We are using TPS54294 in our design, we are surprised why datasheet does not talk about line and load regulation over temperature ( -40 to 85C). This IC has Pseudo osc inside it, what…
Part Number: TPS54394 Other Parts Discussed in Thread: TPS54494 , TPS54294 , TPS542941 Are there any parts like TPS54394RSAR, QFN footprint and pin out but that run at a higher switching frequency?
In the 2A to 4A output range, it doesn't exactly need to…
That EVM is a dual purpose EVM. It supports both TPS54294 which has a power good function for each channel and TPS54295 which has an external slow start for each channel These functions share common pins, 6 and 11. R7 and R8 are used as pull up resistors…
Ramgopal,
Your assessment of the bulk decoupling required is correct. You must calculate the required amount and validate it. The Hardware Design Guide (SPRABI2) discusses this calculation.
This bulk capacitance will affect the control loop on the power…
SI,
Please see the attached presentation. It was originally prepared for the LM10010 which was later superceded by the LM10011 which has higher precision. Please also see the many E2E posts discussing the LM10011 and TPS56121 with C667x and C665x.
