Thanks Tony,
I will read better the TMR's datasheet, then get back more appropriately.
Thank you also for the suggestion of the LDO; it however cannot be employed in my intended circuit, since its input voltage range is between 2.5VDC and 5.5VDC, where my voltage supply would be a Li-I battery...
Although severely harsh, but I cannot say that it isn't 100% true.
The thing is, I am no eletronics engineer. That is why I targeted directly at the technical names of some market-available DC-DC converters. I honestly do not know how to properly investigate a datasheet, as you were expecting...
1) I have referenced to LM1117 as an alternative for the usage of ADP2302, because the first will provoke no noise over the signal read by the TMR2309. The ADP2302, since it operates under a certain switching frequency, might induce some errors over the signals read by the TMR2309. Therefore...
I will reformulate the model:
I have a 12VDC battery. I intend to step-down this input voltage by means of a DC-DC converter to feed by 1VDC four magnetic sensors (TMR2309). The 1VDC is the typical voltage to feed each of the TMR2309, where the latent can withstand a feeding voltage up to 3VDC...
Hi thank you,
I did not understand what you actually mean by "axis".
The major overview of the application is as follows: I need the DC-DC converter to power the TMR2309 as well as an arduino board on which I can perform DAC of the resulting analog signals yielded by the TMR2309. I...
Hi,
I did not understand what you exactly mean by "~14k per axis of ~1k with 3x4 axes".
I did not physically implement the LM1117, but can guess that from 12VDC to 1VDC it would definitely needs a heat sink, and could have performance unstability under sudden load changes/current draws...
Hi,
What do you recommend at best for a DC-DC converter, bucking down an input voltage of 12VDC to 1VDC, noise-freely, with low EMI as possible?
I have been encountered with the ADP2303 but its working principle relies on a switching mechanism, and therefore can induce EMI.
The LM1117-n-7107...
Hi aIbbg,
Thank you for your comment.
According to your reply, I can concretely apply the Biot-Savart law to both a single as well as a stranded wire, and get the resulting magnetic field with a good precision: could you please post some studies/publications/papers stating so?
Nevertheless...
Thank you albbg,
Here's a textual geometric sketch:
1. a 3-p overhead electric transmission system
2. the magnetic field is to be measured with regards to only one line of the three (considering that the distance between line-to-line is wide enough, that the "contribution" of each adjacent...
Moin FvM,
Thank you for your reply. I am targeting for high accuracy. Before subjecting such model to a computer based simulator, I would like to calculate the resulting magnetic field by formulas.
The geometry is as follows: a 70 mm2 stranded aluminum transmission line. The distance from it...
Thank you very much. I still kindly have a concern:
6. No: the geometry of the line hasn't got anything to do with the distance from the line itself and the point P. For example, it is possible to have a straight wire distanced from P by x cm, similarly to a stranded wire identically distanced...
Hi,
I thank you immensely for your drained efforts in realizing the posted reply!
Attached in the same manner is my reply, hoping to hear back from you
Hi
Actually we are not concerned at this stage about the return current: we can imagine it as a delta-configured transmission system (3-phase), where we want to know the resulting magnetic field from the current flow through one of the 3 overhead wires.
Thank you for suggesting the Biot-Savart...
