Tool/software: WEBENCH® Design Tools
Hi all
While trying to create a WEBENCH design with the LM5155 with these (... or similar ...) parameters:
Vin=5V ... 6V
Vout=50V, Iout=1A I get below error message.
Can you look into this ?
Best regards
Ueli

Tool/software:TINA-TI or Spice Models
I converted the PSpice model (for tool TINA) into LTSpice model (file txt with all coordinate) according to the following tutorial: www.youtube.com/watch
In the source file there were macro-block of the component and when I tried to generate the final model the program (LTSpice) is unable to read all its internal macro-block (as if they didn't exist or were not created).
How do I proceed?
Below there is the source file I generated for LTSpice:

Part Number:LMG3410R070
Tool/software:TINA-TI or Spice Models
We want to simulate the behavior of the LMG3410 with different RDRV resistances. For the simulation we did use the given example PSpice and TINA-TI simulation files and varied the resistance RDRV but no change on the drain slew rate was visible. Did we do anything wrong or is the PSpice/TINA-TI model not implemented with this functionality?
Part Number:TIDA-01093
Dear All:
I design the 20s BMS as the TIDA-01093， I have 2 question about the TI design. As below shown
1. I think the MCU SDA , CLK signal can through the Q9, Q10 parasitic diode to connect the BQ76930, that can't by the I2C_CTRL_B control. Is it right?
2. in the I2C isolation application with the ISO1541, I think there is only needs one power cut off the communication. Why do you need to control both power sources? I2C_CTRL_B_U& I2C_EN_U?
Part Number:TIDA-00120
Hi ,
Currently I am using TIDA-00120 design for 12V/24V Lead acid batteries. Can i use this same design for Li-Ion / LiFePO4 batteries of same voltage? Please suggest me on this.
Thanks & Regards

Part Number:TIDA-010047
Hello E2E,
Please le me know about TIDA-010047.
I suggested this reference design to customer. They were interested in it.
If possible, I want to do recommend TI's Nch-FET to them. However, competitor's FET is used on SR for TID.
In this TID, is 100V withstand FET unsuitable?

Dear TI,
I design Pierce crystal oscillator circuit. I face a problem to calculate gain and phase of CMOS inverter.
How to build a test bench to calculate open-loop and closed-loop of CMOS inverter?
Could you please help me to solve this problem since it is not easy to find test bench from text book?
Thank you very much for your help.
BR,
Hieu
Dear TI,
Good day.
We are using the tool board of the above product. (MSP430 controlled Texas instruments EV2400 HPA500)
we didn't have any special problems. However, the error and the problem occurred as follows.
1) Error message : Timeout or unexpected response communicating with device
2) Scanning : It scans very slowly at 30%~.
Do you know what`s problem?
Please help me.
Thanks.
Part Number:PMP20199
Hi Expert,
I have implemented a 54V 30W power supply using the UCC28700. The supply has another secondary winding for 4V output. When observing the start up both the outputs, the 54V output seems to rise above 57V. I think this is causing a Over-Voltage Protection event to take place. Due to this reason the Secondary 2 winding output is dropping for around 100ms. I have attached the startup waveforms for both the outputs.
Can you please suggest a solution.
Thank you.

Mikha.(Please visit the site to view this file)
Part Number:TIDA-01476
Hello Support Team,
Refer the TI design TIDA-01476. It is based on RF networking.
Is it possible to use this design via WiFi networking? I have a WiFi modem. I wanted to access this design on my WiFi network and put the data on cloud so that i can get notifications without any location constraint for the user.
If yes, is there any documentation available for this?
Kindly support.
Thanks.
Part Number:TL760M33-Q1
Tool/software: WEBENCH® Design Tools
Hi
I have Used TL760M33Q1 in my design to bring 24v to 3.3v directly. I am having a problem in its output voltage. It giving 2.1v something. Moreover sometimes it don;t even show any output voltageI
have not put any capacitor at the input and output side of Ldo(TL760M33Q1). Can u please help me suggesting the value of capacitors for the same ...?. In datasheet the vales are given for 6v.
Please look into this on priority
Part Number:TIDA-01471
Hello,
We are evaluating some samples of the TIDA-01471 and get some confusing output we cannot explain. Some plots and the used jumper settings are shown in the attached .pdf document.
1. ADC output changes with increasing frequency
The digital output values are first increasing and then decreasing with increasing frequency. A signal generator is used to produce a sweep from e.g. 100 Hz to 8 kHz with constant amplitude to demonstrate this behavior. The output is 10-20 times bigger on lower frequencies (1 Hz to 1 kHz) than on higher frequencies like 8 kHz.
2. Full scale output of the ADC is not achievable
We tested all possible settings and are not able to get the ADC to full scale output. The maximum digital value is around +-1.000.000 (with J7 and J9 set) and should be 8.388.607 to -8388608 according to the ADS127L01 data sheet. Setting J9 and J7 causes a bad output at the differential amplifier/ ADC input, but a higher output range on ADC. Without J9 set the output gets a positive offset and has a much smaller magnitude.
The ADC is read with a SPI clock frequency of 5 MHz and CRC-8 enabled, thus SPI problems can be ruled out.
Thanks a lot!
Kind regards,
Patrick Oetken

Part Number:SN74LVC1G74
Tool/software:TINA-TI or Spice Models
Hello,
I wanted to see if a SPICE model had been created for this part yet. I was unable to find one through the TI website. Is there one available that can be shared?
I understand that I could create my own and turn it into a macromodel, but I would like to use a "COTS" one if it had already been made.
Thanks,
Mike
Part Number:TPS57040-Q1
Tool/software: WEBENCH® Design Tools
When I go to "My Designs", scroll down to the desired project and click on "Open" the project I've selected doesn't open, it will generally open the project I was last working on (I have several designs with the same IC). Have you seen this before and if so, is there an easy fix to this issue? It's as if the "Open" button is pointing to the wrong project.
Thanks for any suggestions.

Part Number:TIDA-01606
Hi,
I have several questions for the schematic below:
1. why need 10ohm(R33) for the primary side 3V3, but not needed at the secondary side 12V and -5V? And why R33 is chosen to be 10ohm?
2. R10 and R50 are both 0ohm, I guess only one will be soldered in the final board, right?
If we solder R50, then there will be no negative power supply at VEE2. Then do we still need C42, C43?
3. Why R36 and R39 are 3.3ohm? Is it chosen by calculation or by trying different value on the real board?
4. In this board we are driving IGBT with UCC5320. Are there anything different need to pay attention if we are driving SICFET? From both schematic and PCB layout point of view.
Part Number:TIDA-00120
Hi,
I was changed the modifications what you suggested for 48V system from 12V System.
1. MOSFETS Q2,Q3,Q4,Q5 150V rated
2.Resistor divider networks for PV,BV (2.8V )
3. Software: MSP ADC values PV,BV,etc...
then my No Load Test
Input Voltage:60V
Output Voltage:56 (at No Load)
we got the Output Voltage( 56V) 5 to 8 minutes after that Output Voltage is drops to "Zero". then SM72295 MOSFET Driver will damage.

Part Number:TIDA-00366
Hi,
I see you used two power supplies in this design. One 16V and another 5V. Why didn't you make 5V from 16V rail? what was the point for having two supplies?
Thank you
