WEBENCH® Tools: In Webbench Power Designer, time axis has no indication of scale when zoomed in

Tool/software: WEBENCH® Design Tools

The time axis units seem to stay stuck at the zoomed out scale, so you get no indication of the actual time scale when zooming in.  This includes the standard zoom factor for a steady state simulation as shown in this image.

Note the time labels all read "0.3msec"

WEBENCH® Tools/TPS53319: tps53319

Part Number:TPS53319

Tool/software: WEBENCH® Design Tools

 I need a circuit that can supply 10A @ 3.5V to an LED. Using the EVM board and modifying the feedback voltage (R10 and R12 also R23 and R24) to match my LED (3.5 V) I was able to get 10A of current at 3.5V to the LED. I than used webench to create a circuit, but that circuit did not work. The circuit can supply no more than 1.5A before it stops (shouts down). It will restart if the load is decreased, but it will not sustain anything above 1.5A. The major difference between the EVM and the Webench design is the inductor. the orginal EVM board has a .5uH inductor, but the Webench desing used a 1.8uH design. Can you help me figure out why the Webench design fails?

Thanks,

I'm trying to run a transient analysis of my circuit but I get an error message saying I cannot create the file because it is in use by another process. I have already changed the environment variables as stated in this link:

http://e2e.ti.com/support/tools/sim-hw-system-design/f/234/t/741327?TINA-Spice-Tina90-TIen-9-3-150-328

After the first time, it started working for good while, then suddenly I had that same problem pop up and after trying change the environment variables like I did last time I was unsuccessful. I downloaded Tina over 3 times now but no luck. 

Please help. I have uploaded my schematic just in case anyone needs to see it

Part Number:CD4069UB

Tool/software:TINA-TI or Spice Models

Hi dears

I need to use CD069UB in my simulation project with OrCAD P spice. In my project the VDD of IC must to be 15 v. I selected CD4069 from CD4000 library in OrCAD software. it seems that default VDD of CD4069 is +5v.

my first question is:

How can I change the VDD of CD4069 to 15 v ?

---------------------------------------------------------------

I checked the ti.com for finding the library of CD4069 that is designed by Texas Instruments, unfortunately the cite dose not has its library.  

my second question is:

Is there any P spice library for CD4069UB that has good performance (except CD4000 library) and I be able to change its VDD to +15 or other values?

Thanks all

Hi , 

From TINA -TI , I could get many 74HC parts. However 74HC238 or any 238 is not available. Is there any way , we can get this micro in TINA ? 

Is it possible to add 74HC.lib file in TINA?

Part Number:TS5A4596

Tool/software:TINA-TI or Spice Models

Hi,

I am running a transient response analysis of an Opamp based circuit and I need Spice model for TS5A4596.

I have looked and tried but all I can get is IBIS model. Is there any possible way to convert behavioral IO IBIS model to physical level spice model?

If not how can I simulate my design for transient response in TINA TI?

Thanks!

Part Number:TPS51216

Tool/software: WEBENCH® Design Tools

I would like to know about the specifications of TPS51216.
If the output ripple is too small, the D-CAP The jitter may increase and the operating frequency may not be stable.
[reference]
  <www.tij.co.jp/.../jaja465.pdf>

Average: 450 KHz for our on-board power supply with a setting of 400 KHz
It seems that it may move at 2 MHz at the maximum.

[question 1]
In this case, what frequency range should I move?
[Question 2]
I think it has become unstable, but what kind of impact can be considered Is it?
It is understood that the specifications operate with changing frequency, Please let me know.

WEBENCH® Tools/LM27761: WEBENCH not working properly

Part Number:LM27761

Tool/software: WEBENCH® Design Tools

Hello,

The Web-bench power tool for LM27761 (Regulated Charge Pump Inverter) is not working properly. I have used it earlier, but now it doesn't work now. For any valid input setting, the web-bench tool says that the design cannot be created. Even though the input setting which I provide is within the allowed range of values, this occurs. I have attached the snapshot of the input setting which I have provided to the WEBENCH tool. 

Regards, Siva.

Surprisingly, the result of LMG1205 output is not as per expectation. Below is the waveform and schematic added to ADS.

Is it possible to program a blank MSP430, such that it will appear as an USB2ANY interface afterwards?

What we want to accomplish is to integrate the USB2ANY interface on our own board, to have a direct USB connection out.

I have been trying to run a simulation in TINA, but I am getting irregular circuit error message. The simulation I am trying to run is of LM5146-12VEVM. I used LM5146-Q1 PSpice model and connected all the components as per the EVM schematic. I rechecked the circuit and still getting an error. I have attached TINA file.What am I doing wrong??

Part Number:TIDA-00779

Hello,

Can you please explain how the value of R14 is selected. Neither am I clear of the use of D8. I understand that more the Q4 turns on, the more will R14 will come in parallel with R9 and thus, increasing the reference output voltage. Intuitively it feels correct but how do we derive the relation between Vac(IN) and Vout(REF)?
