TPS2X7XX-SCHEMATIC-CHECKLIST: USING PSPICE FOR IT for MONTE CARLO simulations

Brian Leikam — Thu, 14 May 2026 20:26:52 GMT

Part Number: TPS2X7XX-SCHEMATIC-CHECKLIST

Using PSPICE FOR TI, I have set up a TPS7401 voltage regulator and completed a Transicent Simulation. Everything working good.

I now want to do a Monte Carlo simulation on the voltage regulator. Used the following setup, I got the following error. Can you explain what is wrong and how to make the Monte Carlo simulation work?

Hi Brian,

Thank you for asking us!

Try changing the output variable to V(VDDx_1p0) instead of VDDx_1p0. The issue seems similar to: https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1281601/pspice-for-ti-simulation-error-with-lm2743-model.

PSPICE needs the the output variable to be wrapped in a function like V() as if it were being graphed. PSPICE blindly inserts this text into the netlist, which won't produce a valid model card if it isn't formatted the right way. The actual netlist level requirements are on page 45 of this document if you're interested, note how ".MC 10 TRAN VDDx_1p0 YMAX OUTPUT ALL" varies from the examples by the lack of function wrapping it.

Let me know if it still fails and I'll get a monte carlo sim running on my side and we can work from there.

Best,

Gregory Thompson

BQ41Z90EVM: Can't calibrate device batt gain

Pedro Julián Brandolin — Wed, 06 May 2026 16:06:47 GMT

Part Number: BQ41Z90EVM

Hello,

I just got my BQ41Z90EVM. I got to make bqStudio recognize it and flashed the firmware. However, I can't calibrate its Battery Gain. For some reason 10770mV seems to be an out of range value, while it's the real voltage value between BATT+ and BATT-.

Does anyone know why could this be happening?

Thanks,

Julián

RE: BQ41Z90EVM: Can't calibrate device batt gain

Jonny — Fri, 15 May 2026 18:48:28 GMT

Hello,

The voltage applied needs to be scaled by a factor of 1/10. If you are calibrating for 10770mV for instance, then in the calibration tab you will need to enter 1077mV instead of 10770mV.

Regards,

Jonny.

TPS546E25-DESIGN: TPS546E25 SIMPLIS Simulation Error

Buddika Sumanasena — Thu, 14 May 2026 15:06:45 GMT

Part Number: TPS546E25-DESIGN

Hello,

I am trying to simulate TPS546E25 using the TI provided SIMPLIS model and SIMetrix SIMPLIS Elements 9.20i. I get the following error.

*** ERROR *** (TPS546x25_TR_Response.net;248): Decryption failed: Unable to decrypt the data.

Can anybody let me know how to fix this? I have attached the schematic.

TMS320F28379D: Recommendation on using a 0.15 mm wide trace with a ground plane placed underneath for pwm signal routing ??

Haseeb Afzal Mir — Mon, 11 May 2026 20:58:18 GMT

Part Number: TMS320F28379D

Hi , I was looking to develop the control card housing 7 differential sensing and conditioning circuitery . Analog protection . 16 epwm's and many gpio's .

I was looking for some hardware reference guide particularly on the PCB front .

Like I am using a 6 layer board with the stack looking like

Layer 1 -- Signal

Layer 2 -- GND.

Layer 3 --- PWR ..

Layer 4 --- Signal ..

Layer 5 ---- Ground .

Layer 6 ---- Signal .

.Also I am using Analog tool of TI to calculate the trace width I require to route the traces . For epwm's especially . I switching frequency is going to be 500 KHz . LLC converter . I calculate the trace width required to achieve it is 0.15mm . But the wider trace gives low inductance . Which one is recommended ?

Any reference guides on PCB front ?

Thanks

Trace length is 70 mm.... And trace width is 0.2 mm ..... Its separated from the analog circuitry with a ground plane beneath it all throughout .

RE: LM61480: Deviations in datasheet specifications and Webench design

Naresh Adepu — Wed, 13 May 2026 09:31:28 GMT

Hello Irene

WEBENCH is a good starting point but it uses generalized models, so I would recommend relying on datasheet recommendations because they are specific to the device and are actually based on silicon data. You can validate every component against the datasheet component recommendations and use them accordingly in your design.

if you have final schematic that needs to be reviewed, we would be happy to support. Please share another request accordingly.
thanks and regards

Hi,
I have found differences in datasheet specifications and Webench design, so I need to know which one is to be followed. Please find attached the Webench design I've obtained for the above mentioned buck IC. This is found deviating from the design specified in the datasheet.
Vin = 20 V

Can I please have a 3D CAD model of DP83867ERGZ-R-EVM? Preferably in the form of a STP file or Allegro files, I cannot open the Altium files provided with my software. I had to put a different PN in the field above because it would not let me use DP83867ERGZ-R-EVM.

Peter Luong — Tue, 12 May 2026 22:04:11 GMT

Hi Haseeb,

If you are only designing for sensing and control circuitry, then the controlCARD itself will likely be smaller. In that case, note that impedance and termination have reduced impact for short traces (<3 cm trace length). If you have already routed the ePWM traces, what is the trace width?

Peter

The Tina DRV110 simulation example doesn't seem to work properly and immidiately goes to pwm and not peak current so waveform is not as the datasheet would imply.

Hello Micheal,

Thank you for your patience.

The SBWM004A.TSC works as expected.

Please increase simulation time in transient analysis and separate curves from View menu. Please let me know if you have any questions.

TIDA-020033-TD-DESIGN: Request for Access to TIDA-010269 Design for R&D Use

chandran bose1 — Tue, 12 May 2026 04:24:57 GMT

Part Number: TIDA-020033-TD-DESIGN

Dear TI Support Team,

Hi, this is Chandran from IIT Madras.

I would like to use the TIDA-010269 reference design for our research and development work.

I previously contacted Bill Xu (bill.xu@ti.com) by email, and he informed me that access to this design is covered under a Non-Disclosure Agreement (NDA). He suggested that I contact the local TI support team or post on the TI E2E Support Forum for guidance.

Could you please let me know the procedure to obtain access to this design and complete any required NDA formalities?

Thank you for your support.

Best regards,
Chandran
