Tool/software:TINA-TI or Spice Models
Hi,
I have bode plot of an open loop feedback circuit like this:
The top plot is the gain.
Is this possible to take a reciprocal if the gain in frequency domain, attenuation = 1/gain in TINA?
Or some circuit can do this?
so magnitude plot would look like this:
Thanks,

Part Number:PMP7760
Hi,
I have a unique automotive system in which I'm trying to drive high powered LEDs (Around 6W in total, possibly 9W) using a 510V input. The LED driving side needs to be isolated.
The reference design I found (PMP7760) seems all good except in the bill of materials there seems to be one part namely the Flyback Transformer (Part Number G094215LF) by Gci Technologies that is virtually non-existant anymore. It is not available anywhere I checked.
My question is: Q1: Are there any alternatives that you can suggest that would work in this case? I have access to the data-sheet (posted on a previous thread on this forum), I just need info on if TI has any other reccomendations on what I could use instead of the G094215LF.
Q2: Is it possible to find a flyback transformer that would replace the G094215LF but provide an output at 12V instead?
Part Number:PMP20588
I am using PMP20588 Fully Autonomous Single Port Type 2 (30W) PoE PSE Reference Design without any changes in the schematic and BOM. While testing the board i can see output voltage as 23VDC instead of 54VDC.
Please help me to get the required output voltage(54VDC). Do i need to make any changes in the schematic?
Regards

Part Number:CSD18509Q5B
Tool/software:TINA-TI or Spice Models
Hello E2E,
I analyzed to check turn on/off delay time and rise/fall time of spice model, but it was a very different value compared with the data sheet.
At the time of analysis, an ideal pulse (rise/fall time 1ns) was added to the gate, and a circuit was created according to the test condition described in the data sheet.
(Analysis value : Turn on delay time 5.5[ns], Rise time 3[ns], Turn off delay time 15[ns], Fall time 4.5[ns])
Is the turn on/off delay time and rise/fall time modeled in the spice model of the CSD18509Q5B element?
Thank you very much.

Dear Specislists,
I am using WEBENCH.
Vin:22-26V
Vout:5V

At this time I can't make a PDF design file(Design Documentation).
Recently this problem has occurred in some devices.
Could you please confirm and repair.
I appreciate your great help in advance.
Best regards,

Part Number:INA169
Tool/software:TINA-TI or Spice Models
Hi, I'm trying to design with the INA169 for use in a relatively high speed current control feedback loop. I require bandwidths well into the 100s of Khz, and the INA169 if operated with a low output gain (RL = 1K) can deliver the required performance and seems to be the only current sense architecture that achieves this bandwidth with the high Supply voltages I'm using (60V). However when I simulate with TINA, I see an output current in the order of 25uA, when I have zero input. I verified this with the input pins shorted as well as in circuit.
I need to amplify this output and must keep the gain of the INA169 very low in order to achieve the required bandwidth for the loop. Therefore to overcome this offset I will require a precision offset circuit, adding delay and noise, therefore I would like to avoid if possible.
Before I proceed further, could you please confirm that this output error (quiescent output current) is actually real, does the actual component do this? In the datasheet I only see details for output error as a percentage of differential input. This clearly shoots off in a negative manner as Vin falls towards zero. However if this error is a percentage of zero then it should theoretically be negligible. This is not what I see when I model in TINA.
What does the real IC do?
Thanks

Having looked through the schematic, I have several other queries:-
Part Number:TMDSDSK6713
Hi. I am Ammar from NUST, Pakistan. I am currently working in DSK6713 floating point DSP. But now i need to shift to a high speed kit DSK6455 which is fixed point. Will my programs run in that kit? Because i need high speed DSK. If not, kindly refer me to other Floating point high speed DSP kit

Part Number:TIDA-00164
Hello
My purpose is to develop the tida-00164 board.
From your database I downloaded two files.
I downloaded the first file "tidu365b.pdf" (i.e. File_1) from link www.ti.com/.../getliterature.tsp
and the second file "tidr962.pdf" (i.e. File_2) from link www.ti.com/.../getliterature.tsp.
I compared the component list in File_1 pages 34, 35 and 36 vs. the list in File_2 and found the following differences.
1 -
File_1 rows 08 & 09: the capacitors corresponds to the capacitors in file_2 row 09 for what concern their numbering, but not for the capacitance values.
In File_2 they are all the same capacitance, while in file_1 they are divided into two groups with different capacitance values.
From the schemas in File_1 page 32 it seems that the correct capacitance values for C12, C24 etc. is 0.027uF, and so, the correct BOM is the one in
the same document page 34 row 9.
Q1: Could you confirm please that File_1 rows 08 & 09 are correct while file_2 row 09 is not?
2 -
File_1 rows 25 and 76 correspond to File_2 row 25 but a different number of shottky diodes are foreseen.
In File_1 page 30 there is a D4 diode (just below and on the right respect to D10 diode) that seems not connected to other components!
Q2: Could you please confirm that this D4 diode is not used, and the only D4 used is the one in the upper part of the same schema?
3 -
File_2 rows 31, 32, 36 and 71 have no correspondence in File_1. Probably it isn't a problem!!!
Q3: Could you confirm please?
I think that the correct component list is the one in file "tidu365b.pdf" pages 34, 35 and 36.
Q4: Do you agree with me?

Somewhere (I don't remember exactly where) I found that the board reference data are:
----------------------------------------------------------------------------
Customer : TI
Card Name : ISE-PLC-AIM-200 REV E1
Part Number : -
Date : 03-06-2014
Designed At : Tessolve Semiconductor Pvt. Ltd. --- "Excellence" 5th Floor, No.104, Race Course Road, Coimbatore – 641 018

I already tried to contact them using the sales@tessolve.com e-mail address but got no answer. (My purpose was to ask them to build a board for me).
Q5: Do you confirm that the board has been built by Tessolve Semiconductor?
Q6: Do you have any different e-mail address I can use to contact them?
Thank you very much for your help.

Dear Sir,
The output Ripple is around 160 to 140 mV with 20 MHZ band limited Scope.
Is there any suggested ripple suppression filter or any other circuit modification such that the ripple can be reduced to a level of 10mV.

Hey there,
I guess there is an error in the schematic shown in the webbench (pic below). According to the datasheet, Ccomp2 should be connected after Rcomp. Furthermore it is stated, that PRE should be connected to SW, which also is not the case in the webbench. (at least i did not find anything in the datasheet that says that it shouldn't be connected)

Hello Everyone.
Its always a great option to post a query in this community.
I am trying to replicate the circuit shown in the reference design guide for simulation purpose.
But I am unable to find the part "LM4041" (which is a voltage shunt reference) within the TINA-Ti library. And eventually, I am getting erroneous results. Is there any method to obtain the part within the software?
Part Number:OPA836
Tool/software:TINA-TI or Spice Models
Dear TI Users,
I have a question regarding the simulation of the OPA836 in TINA-TI. To double check my low side current sense circuit performance, I started a simulation in TINA-TI, that you can find in the attachment.
Unfortunately, I see that the output voltage of the OPA836 can reach at minimum just 110 mV and not nearly 0 V (See figure). When I exchange the opamp with another Rail-to-Rail opamp, it works.
So, could you please tell me, if there is an error/misunderstanding with the model/simulation, or if the model is just not accurate enough?
Thanks in advance.
Best Regards,
David

Hi,
I'm unable to open the Altium CAD files with Atium software, an error message saying " "File name" has invalid format". Am I able to get the files converted to Eagle or another software instead?
