Part Number: TPS6288X-Q1-DESIGN

Does anyone have a .tsm file to import into TINA-TI for circuit simulation? Thanks.

Hello Kira,

Thanks for sharing the details! Unfortunately, we can not provide un-encrypted model without NDA.

Thanks,

TPLD1201-Q1: Rising Edge Retrigger

Mohan Kumar — Mon, 28 Sep 2026 05:33:05 GMT

Part Number: TPLD1201-Q1

Hello,

I require a rising-edge retriggerable pulse detector with the following functionality:

When a rising edge is detected on the input pulse, the output should go HIGH and remain HIGH for 800 ms.
If another rising edge is received before the completion of the 800 ms period, the timer should reset and restart the 800 ms timing period from the latest rising edge.
If no new rising edge is received within 800 ms, the output should go LOW.

Could you please review the attached TPLD configuration and confirm whether it is correct and satisfies the above requirements?

Please let me know if any modifications are required.

Hi Mohan,

I do not recommend your current configuration because when IO1 is not active, you will get a continuous set of pulses on the output.

What kind of accuracy do you need?

I suggest trying something similar to the below configuration. Keep in mind that the delay will have a two-clock-cycle sync period the first time it is triggered that will not re-occur during re-triggering.

Regards,

Nikki

PSPICE-FOR-TI: TPS62902: startup waveform changes when only transient stop time is changed

Donghyeon Min — Fri, 09 Oct 2026 10:44:27 GMT

Part Number: PSPICE-FOR-TI

Hi,

I'm seeing different startup results with the TPS62902 transient model in PSpice for TI 23.1.0 (30 January 2024).

Using the supplied STARTUP circuit, I ran two simulations in fresh PSpice processes, changing only the stop time:

.TRAN 0 1m 0 20n
.TRAN 0 2m 0 20n

The circuit and model are identical. Both save EN, VOUT and SS/TR, and use ADVCONV, ABSTOL=1n, ITL4=50 and RELTOL=0.002. These are adjusted diagnostic settings, not the default profile.

Both runs complete without errors. However, near 900 us, VOUT is about 0.508 V with the 1 ms stop time and 0.000603 V with the 2 ms stop time. In the 2 ms run, VOUT rises to about 0.297 V around 776 us, then falls toward zero. An earlier 2 ms run produced the same waveform.

Is there a recommended solver setting or model update for this? I'd like to understand why changing the stop time changes the waveform in the earlier part of the run.

I've attached the inputs, output logs and one comparison plot. The original DAT and CSV files are available if needed.

Thanks.

RE: TPS2663: ERROR(ORPSIM-16362): Name on .ENDS does not match .SUBCKT

Jai Varma — Mon, 12 Oct 2026 07:35:28 GMT

Hi Hemanth,

Thank you for your response. Using the example schematic, I was able to simulate the circuit, though if I follow the usual steps of importing a library and generating the part, I am unable to simulate the part in that case. I copied the symbol from the example schematic and added the library in the simulation profile, and I am able to simulate the design.

Regards

TPS2663: ERROR(ORPSIM-16362): Name on .ENDS does not match .SUBCKT

Jai Varma — Tue, 06 Oct 2026 06:55:41 GMT

Part Number: TPS2663

I am trying to simulate TPS26631RGER in PSpice for TI using the official library. I have updated the library in the library section of the simulation profile. I have placed the library in the project folder. I checked online, where they suggested copying the entire library and pasting it into Notepad, and checking for "CRLF" as some ending characters may get cut and cause the error.

Yet, it's still giving me this error: ERROR(ORPSIM-16362): Name on .ENDS does not match .SUBCKT. Please suggest how to proceed.

RE: TAS67534Q1EVM: Cannot install TAS67534 application in PPC3

Shadow He — Sat, 10 Oct 2026 01:48:00 GMT

You could try manually install it.

Follow below link, and download the .tar.gz file.

https://www.ti.com/secureresources/TAS67534-TAS67624-GUI

And the file could be installed by PPC3, as below picture example.

When I try to install the TAS67534 EVM App in the latest PPC3 release, I get a message saying "Problems occurred during installation of TAS67534_67624. Refresh Available EVM Apps before trying again." I attempted the suggested refresh several times, and I kept getting the same failure and error message.

Please advise on how to proceed with the installation.

LM5046: LM5046 slope compensation resistor selection issue

Guangzhi Cui — Thu, 08 Oct 2026 03:24:41 GMT

Part Number: LM5046

Hi, Teams

When I check the datasheet of LM5046, I found the slope compensation resistor Rslope is calculated as 1.67kohm based on the equation. But in the schematic, the actual value is 3.48kohm (already doubled). Why it is not same as the calculated value, is there any consideration about it? How clould I select this value, also double it based on the calculation value?

RE: LMR38020-Q1: Bode Plot Issue for LMR38020

Tony Koulong — Fri, 09 Oct 2026 20:34:35 GMT

Hi Ani,

I don't think you did anything wrong, but a transient model are usually not good to run boding measurements. You need more like a frequency domain which we don't have.

LMR38020-Q1: Bode Plot Issue for LMR38020

Ani D — Fri, 09 Oct 2026 06:15:54 GMT

Part Number: LMR38020-Q1

Hello,

I had designed a 48V->12V buck converter using LMR38020. I got the model and used Pspice for TI. The Transient Simulation is working fine. I wanted to do the stability analysis using Bode Plot. I am getting my gain plot starting at -48dB instead of 0dB. Have I done something wrong? I used the default Bode Plot (dual Y axis) marker.

RE: UCC28C43: Old Revision W/ Alternate Characteristics

Adhvaidh Aravind — Fri, 09 Oct 2026 17:57:24 GMT

Hi Kamden,

Thanks for reaching out via E2E, and apologies for the delay.

The new devices will only follow the latest datasheet (yes, it will "only verify the new window"), and not the old one.

This is because, for the new material, the the internal bias voltage of the error amplifier is generated in a different way as compared to the old material, due to process technology differences:

Let me know if you have any further questions.

Best,

Adhvaidh

UCC28C43: Old Revision W/ Alternate Characteristics

Kamden Collins — Thu, 01 Oct 2026 22:11:38 GMT

Part Number: UCC28C43

Three paramaters have changed in the latest datasheet revision bewteen the August 2001 and June 2024 copies available online. The new revision has a VOH min limit of 4.8V with a VREF = 5V.

The old version has a VOH min limit of 5V. With the error amplifier tied to VREF, 5V is the max the error amp can go.

During up-screening we are seeing the newer date codes be unable to achieve the old characteristics of VOH and wanted to reach out and see if there was a chance that you'd know if the devices should be able to pass the old requirement or if manufacturing alterations have reduced the window to only verify the new window?

RE: LM5046: LM5046 slope compensation resistor selection issue

Adhvaidh Aravind — Fri, 09 Oct 2026 15:00:43 GMT

Hi Guangzhi,

I understand the confusion here.

Yes, if you plug-in R_CS= 15 Ω (or an effective of 150 mΩ due the CS transformer) from the old revision of this EVM, you'd get R_{SLOPE ~} 2.62 kΩ

But in the latest revision of the EVM, the R_CS has been changed to 18.7Ω (or an effective of 187 mΩ due to CS transformer); the datasheet has the schematic from the old revision I suppose. The same has been reflected in the design calculator.

If you plug-in this updated R_CS value, you'd get 3.26 kΩ, and the next standard resistor value was chosen.

Thanks.

Best,

Addy
