TIDA-00951: Calculation of Cclamp capacity value in TIDA-00951
Part Number:TIDA-00951
Hello.
Thanks a lot for your help.
There seems to be no formula for obtaining Cclamp capacity in the document provided by TIDA-00951.
Could you tell me the formula to get Cclamp capacity?

WEBENCH® Tools: Support Required for selecting Buck boost converter
Tool/software: WEBENCH® Design Tools
Hello All,
We require Buck-boost converter with input range 3.3V to 24V and output range 3.3V, 3A.
We tried the following ICs,
1. LM338T/NOPB
2. LM26003MH/NOPB
3. TPS54331DDAR
With the above ICs, the input range achieved is 4V to 24V. Whereas our requirement is to have an input range between 3.3V to 24V.
Please suggest an appropriate IC or tested circuitry for the above mentioned ICs.
Thank you,
Sandhya

WEBENCH® Tools/LMZ10500: Vout Tolerance
Part Number:LMZ10500
Tool/software: WEBENCH® Design Tools
If I customize Vin=5.0, Vout=0.6, Iout=0.25, select modules, then the LMZ10500 design and customize, it shows on the overview GUI a Vout Actual of 22.7V and gives me a Vout Tolerance of 67.6 % in the design report. Can you advise, and also tell me specifically how Vout tolerance is calculated in the design report?
Results shown in the attachments.

TINA/Spice/LMG1210: PSPICE model
Part Number:LMG1210
Tool/software:TINA-TI or Spice Models
LMG1210 spice model from TI website is not applicable in ADI's simulation tool "LTSPICE". It always gives the error of "too few nodes". Probably it is encrypted and it can't be recognized by LTSPICE. I downloaded LMG1205 spice model from TI website, which is perfectly fine with LTSPICE. Just wonder if you can provide the same type of model for LMG1210?

Tool/software:TINA-TI or Spice Models
Hi,
I would like to use TINA to simulate TPS562210A. I tried to import the Pspice model provided by TI using "New macro wizard". However, at the very last stage it gives me the error of " The device is not found".
I appreciate if you could provide me with the unencrypted version of TPS562210A.

TIDA-010030: Reversed charger protection circuit
Part Number:TIDA-010030
Hello;
I'm unclear as to the functionality of what I "assume" is the reversed charger protection circuitry. If my assumption is incorrect, would you please explain the function of the two circuits involving Q22 and Q23?
1. If my assumption is correct, please explain the purpose of circuit involving Q22? I've typically only seen the DCHG fet disabled, but Q22 seems to be there to disable the charge fet. And if so (?), it couldn't anyway since the CHG fet's body diode would still conduct??
2. If a charger were connected, and both the CHG and DCHG fet's were OFF, it would seem that D40 would pass the charger's voltage directly to the 76200's DSG pin? Is that permissible?
Thanks

TINA/Spice/SN74LV4051A: Using the SN74LV4051A in LTSpice
Part Number:SN74LV4051A
Tool/software:TINA-TI or Spice Models
Hello,
I've imported provided model of SN74LV4051A demux for Spice from the TI website. But unfortunately I have problems using it. From what I've read in the datasheet when the INH signal is 1 then it should not let any signal come to the output. But in my case no matter what the values of INH, A,B and C is, there is always the signal from the Input (COM) on one of the outputs (Y0). I'm even not using it in any circuit it's just this demux connected to some voltage source to see how it should work. Could anyone please tell me what am I doing wrong? I'm attaching my circuit.

Hi team,
My customer is designing their prototype referring to TIDA-080004.
The pull up voltage of 3.3V for HDMI HPD signal is regulated on the board, it does not use 5V provided from HDMI source.
Is there any special reason or benefit? Please advise.

TIDA-00322: Not able to use TDC1000-C2000EVM GUI with Custom Board using ATMega328P
Part Number:TIDA-00322
Hi, I've developed a Custom board like TIDA-00322, using ATMega328P instead of TMS320F28035. I've checked the board using an oscilloscope and the waveforms that I'm receiving are matching to those mentioned in the datasheet. I'm using Arduino for writing the code. I wish to use TDC1000-C2000EVM GUI for debugging purpose by changing the register values but that's not happening. After connecting my board to the Laptop, and selecting the COM13 as the Serial Port from the Setup tab in the GUI, and clicking connect, "Connect Failed! Check the COM port number." I've tried plugging the device into different USB ports, but the result is the same. Also, COM13 is the only port available, therefore there's no chance of selection of wrong COM port.
Is the connection of GUI to the Custom board running on ATMega328P not possible or what? Help would be much appreciated.
Thanks & Regards
