I've a simple question : does TINA-TI support the Jiles-Atherton model ????

I wrote recently the following PSPICE model for aa simple  transformer but the model doesn't work

.More the transformer works as an  ideal transformer without taking in account the suggested  magnetic model of the core !!!

he N67 is an old ferrite material from EPCOS and was replaced,I think, with new N87 type .With 40  turns, the primary current must have a (+/-) a Lp=3.56mH and the magnetic component of primary current should exibit a sawtooth with a Im,pk=0.64A nevertheless nothing of this happens……….

Hi Team,

I have aquestion about FPD-Link3.

I am looking for a conversion device from eDP to FPD-Link3.
I couldn't find it on TI's web.
I think eDP / DP and MIPI will become mainstream in the future panel market.
Will you develop FDP-Link3 products that support eDP in the future? Is it under development?

TIDA-01243: HDMI+USB+12V over USB Type C

$

Part Number: TIDA-01243

We are looking for a solution to combine USB, HDMI and 12V power over USB Type C. We currently have a motherboard that outputs USB and HDMI which we connect to a touchscreen display. We are hoping to redesign the motherboard and the display electronics to be able to use a single USB Type C cable between the motherboard and touchscreen display. The new display will use 12V power, so I'd like to send that over the same cable as well. What ICs should I consider for combining the signals on the motherboard as well as demuxing at the display electronics back into USB and HDMI? Any reference designs would be great.

I was referred to the TIDA-01243 reference design, which looks like it would work for demuxing the signals at the display into USB, HDMI, and 12V power. I wasn't sure if it would work for muxing the signals at the motherboard. A few more questions I have about this design:

-Why do I need two controllers - TPS65982 and TPS65986?

-It looks like I need to convert HDMI into DP for this to work. What ICs should I be looking at to convert HDMI into DP?

-I am ultimately going to be converting to LVDS at the display, are there any ICs that convert DP to LVDS? If not, what ICs can I use to convert DP back into HDMI (I have found designs to convert from HDMI to LVDS)?

I'm pretty new to USB Type C and Alt Mode, so any help would be greatly appreciated!

Part Number: PMP11107

Hello,

The reference design PMP11107 is presented as a PoE class 3 application and for an input voltage range from 36V to 57V.

I would like to know if it is possible to supply the circuit with 12V and if this design can be used in class 0 as the TPS23753A is able to do.

Thanks, regards

TIDA-01606: How to modify from 3-phase to single-phase system?

$

Part Number: TIDA-01606

Hi Champs,

My one customer wants to refer TIDA-01606 for single-phase grid tie inverter.  Here are some questions about it.

Q1) The user’s guide of this reference design has a guidance of LCL filter design. I think all the equations in LCL filter can be used for single-phase inverter with just changing the coefficient sqrt(3) to sqrt(2). Is it correct? If not, woud you give me some advice?

Q2) If this topology can be used for battery charging with bidirectional mode, In-rush current will come from grid to high voltage capacitor through body diode of SiC when relay on the grid side turns on. In this scenario, do you need an in-rush current protection circuit?

Thanks,

Steve

 

CCS/TIDA-01604: TIDA-01604 bipolar operation

Part Number: TIDA-01604

Tool/software: Code Composer Studio

Hallo,

is it possible to use this Design in bipolar Operation?

We want to control big magnets, and during fast switching off the Magnet there is a amount of Energy to dissipate.

In this situation  the DC Link Voltage of our Control Unit rise up.

Therfore I want to use the PFC-Stage to bring the Energy back to the GRID. (see Page4 TIDUE54A "A totem-pole PFC is inherently capable of bidirectonal operation")

WEBENCH® Tools/LM3478: unstable as voltage is varied input or output or as current increases.

$

Part Number: LM3478

Tool/software: WEBENCH® Design Tools

Using the exact schematic and BOM as Webench suggests, output is only stable at certain voltage inputs or current outputs. Else it becomes wildly unstable with any changes. For example, if the input is varied from 3.0 to 4.2V (Li-Ion source) and output is set via feedback resistors to 12V, it becomes unstable at 3.6, then somewhat quiets down until 4.1V then output becomes wildly unstable, then at 4.3 it works perfectly again. Same goes for varying current load. It is stable with zero load, but add even a 100mA load (Webench was asked for a 12V @ 2.5A output) and output goes into wild oscillations and unstable output. THe only stable mode seems to be at 3.0V where everything works perfectly. AS soon as V goes above 3.5v output becomes unpredictable. Power supply isn't the problem; adding caps at FB only lowered oscillations or in some cases made it worse.

Part Number: TIDA-01410

To TI Application Engineer,

I have trouble making TIDA-01410 work properly. 

To start with, I downloaded Gerber files and manufactured the PCB/populated the board. I used USB2ANY for interface, and updated firmware. I tried to lock to a few test frequencies on one of the RFout ports, but it seems the output is not locked. Note I used signal generator output, instead of an external board housing a crystal oscillator (not sure if this is the cause). Plus both LED LD indicator light didn't light up after succesful downloading. I have captured a couple of outputs on Spectrum Analyzer, please see below:

1. Ideal frequecy configuerd on TICS Pro software = 400MHz

2. Ideal frequecy configuerd on TICS Pro software = 600MHz

Can I have any guidance on how/where to debug, or where to look for debugging materials? 

Thanks,

Xiaomeng

choosing of full bridge gate drivers

Hi, i am here to put a question for you peoples who can help me exactly, .......

          Actually i am trying to make the DC/DC converters using full bridge topology for the higher power rating, my input supply is single phase 230V/50HZ.

    right-now i dont have ideas about gate drivers for full bridge method, but i am clear in the concept-wise switching which the four drives will works with sequential propagation delay for each power mosfet.

 if ex. we take power MOSFET as 600V/ 30A or power IGBT as 600V/30A, connected in full bridge setup and the switching transformer is 3KW power rating and switching freq is optimum as kHz and above, so can anyone please suggest me some ideas about this topology and about gate drives  which means how can i achieve the variable delay for each gate drives as some propagation time delay with proper working control systems.

 also please suggest me what kind of the IC's will be used for this setup which is driver IC, PWM generator IC, and gate driver IC in made of TI itself. 

i hope this will understand for you guys, so i am eagerly waiting for those peoples kind suggestions.

TIDA-01575: Sensor and Signal Conditioning Board

$

Part Number: TIDA-01575

Dear Sir/Madam, 

I have doubt on " Sensor and signal conditioning board" details in Reference design . Page no 11 in reference design (para below) . 

Sensor KXTC9-3672 has 220mV/g sensitivity --- it means for low rpm motors , pulse shock is around 0.01g , so output is 2.2mV. For +/- 6g  the voltage will be +/- 1320mV. total voltage range can be 0 to 2640mV. 

ADC resolution is 14bit , resolution per bit of 152.58uV. Total voltage range is 2.5V. 

so Why we are adding amplifier stage ? when sensor output range is in range of ADC range. 

I didnt understand the sentence "This difference in LSB is insufficient for resolving the vibration, which means a low noise amplification stage is required to improve the sensitivity of the vibration"

 

For example when we add amplifier,  for high g values like 5 and 6 , the amplifier output will sature. SO please can you explain ?

"""""

The micro-electro-mechanical sensor (MEMS) accelerometer selected for this application is the KXTC9- 3672 from Kionix. The output sensitivity of the sensor is typically 220 mV/g with a full range of ±6 g. Depending on the application requirement, the pulse shock generated by the motor may be of the order of 0.01 g to 0.1 g depending on early failure detection. For motors that run at a lower rotation per minute (RPM), the pulse shock is 0.01g. Hence the output of the sensor would be of the order of 220 mV/g × 0.01 g = 2.2 mV.

The integration precision ADC on the MSP432P401R device with a 2.5-V reference yields a resolution per bit of 152.587 µV; therefore, the effective vibration detected would be of the order of a 14 LSB change. This difference in LSB is insufficient for resolving the vibration, which means a low noise amplification stage is required to improve the sensitivity of the vibration. """"
