Part Number: TPS40428 Hello,
TI fusion power design could detect the controller TPS40428, but it shows fault CML.
Please see the attached.
Please let me know what's the 'CM'L fault means.
Thanks,
Srinivas
Part Number: TPS40428 Other Parts Discussed in Thread: CSD95378BQ5M Hi Team,
We were testing our unit in thermal chamber, at 55C (chamber's temperature).
The unit didn't come up some times until we do power cycle.
In the state where the unit didn…

Hello,
Please see below snip from TPS40428 datasheet. We could able to meet the power-up requirement.
Is the power-down requirement is equally critical? Please see our design power-down.
Yellow VDD (5V) of the power stage…
Part Number: TPS40428 Hello TI,
We got our boards with TPS40428 and started testing. I see lot of ripple (especially HF) at the output.
I tried to optimize, but didn't reduce drastically. Please find the attached schematic and measurements.
Please…
Part Number: TPS40428 Hi TI Expert,
We used TPS40428+CSD95378B in my design, TPS40428 is powered from P12V, power stage VDD is connected to P5V, which is generated from P12V through a buck converter.
Is there any delay time requirements between P12V…
Part Number: TPS40425 Other Parts Discussed in Thread: TPS40428 Hi TI team,
1). We are planning to use the TPS40428 in place of TPS40425 and TI provided the list of changes in TPS40425 programming file to use for TPS40428.
As the PEC is true in the…
Part Number: TPS40425 Other Parts Discussed in Thread: TPS40428 , We are using TPS40425 in our projects at the moment. However due to material shortage, we are planning to use TPS40428 as an alternate part. We see that both TPS40425 and TPS40428 are pin…
Part Number: CSD95378BQ5M Other Parts Discussed in Thread: TPS40428 Hello,
I don't have TPS40428 EVM.
I would like to know state/voltage of Vsw pin of CSD95378B when TPS40428 is not powered up i.e. no 12V to VDD of TPS40428, but 12V to VDD and 5V…
Hi Bruce,
For #1, TPS40428 can support 30A for each phase. However, it also depend on the system thermal design. If low temperature is needed then the supported current per phase will be reduced.
For #2, Yes, the table is showing per-phase current…
