Part Number: TPS40400 After the adapter was used for many times, it suddenly appeared abnormal. The software kept displaying no usb, and the adapter was very hot. Our use method is to connect the 10-pin terminal of the adapter to the product and the digital…
Part Number: TPS40400 Other Parts Discussed in Thread: TMS320DM8168 Hi All,
We are using TPS40400 in our design for supplying AVS core supply to TMS320DM8168 processor. The address of the TPS40400 is programmed to 0x38(70 in octal) using resistors.…
Part Number: TPS40400 Hi Team,
during test on EVM, we find Vout reading through GUI is lower than voltage measure on Vsns+ - Vsns- . Please kindly see below.
test point on EVM : TP6 and TP18. TP6 and TP18 is connected directly to Vout and GND through…
Part Number: UCD3138 Other Parts Discussed in Thread: UCD9240 , UCD90120 , UCD7231 , TPS40400
Hi Amiel,
With your help, I could have a PMBUS custimized GUI that could be able to communicate UCD3138 device.
But one proplem is that scan device in…
Other Parts Discussed in Thread: TPS546C23 , TPS549A20 , TPS40400 Hi,
We have a requirement of digitally (I2C) programmable buck converter to configure output voltage & output current.
Below are the required parameters for buck converter selection…
Part Number: TPS40400 I designed a tps40400.
But there is no output. Circuit is same with your webench.
BP3, BP6,VDD pin voltage is normal. There is no switching signal.
GUI status error is Vout OVF.
I don't know what's problem.
Part Number: TPS546D24A Other Parts Discussed in Thread: TPS546C23 , TPS546C20A , TPS40400 , TPS549D22 I would like to use TPS546D24A, but the manufacturer is out of stock. Which component should I use?

It will depend on what PMBus features they are looking for and the range of output adjustment for a single output.
For converters with integrated power FETs, our PMBus solutions are designed for considerably higher current levels…

The VDD bypass current has a small positive temperature coefficient, but the dominating contribution to the variation in operational current is part to part variation.
Operating at a specific condition will not significantly reduce…
Part Number: TPS40400 Hi Team,
Would you advise what condition does Ivdd become max of 15mA specified in datasheet below?
I'd like to suggest lower power consumption usage to the customer.
So please help to advise it.
Thanks
Best regards,…
Thank you Daniel.
Most likely, the 10k pull-ups to a 3.3V rail were not providing a fast enough rise-time to effectively create "logic 1" values for 400kHz communications. I am glad we were able to address the issue.
Hi Peter,
My customer changed the pull ups on the board from 10kohms to 2.2kohms. I2C communication picked up after that. Thanks for your help.

The first item that I see is that the interface dongle is configured for Open Drain, so the interface is relying on pull-ups on the board, so double check to make sure the board they are interfacing with has on-board pull-ups for the…
Part Number: TPS40400 Hello,
I have a customer who has designed the TPS40400 onto their board, and they are having an issue connecting to Fusion Power Designer. They are using the TI USB Interface Adapter (connecting only SDA and SCL, not the Alert…

If they do not need PMBus, there are a number of possible solutions they could consider, depending on the application needs.
TPS40101 is a voltage mode control controller capable of operating upto 1MHz switching frequency with drivers…
Hi Miller-san
Thank you for the advice and sorry my insufficient explanation.
My customer is looking for proper controller for high efficiency GaN power solution for consumer product
such like 2cell voltage system.
The customer is designing based…

No, the TPS40400 does not have a low-power function that would reduce the VDD current to 4mA.
If they do not need PMBus Telemetry, we have alternate devices that are able to support a sub-4mA VDD bias current.
Please see the TPS549B22…
Part Number: TPS40400 Other Parts Discussed in Thread: TPS549B22 , TPS549D22 , PMP21440 , LMG1210 , TPS40101 , TPS40322 Hi Team,
Would you advise does TPS40400 have power saving internal register setting or
external part which can save power?

Yes, the maximum duty cycle of 85% at 1.2MHz is measured with the 2.2nF loads added to the gate drivers. This loading increases the minimum OFF time by the high-side rise time but decreases it by the high-side Falling time. Since the falling…
