I think you misunderstood how the UVLO works. I think with your selections of 10 and 490 kOhm, your V_ON is going to be 17.5V and the V_OFF is 12.65V. 0.4V on the EN pin is when the chip wakes up, but the output is only activated at 1.263V.
@aatmanp Ай бұрын
Hey there, one question regarding the output power being 120W. On what basis did you consider it? Also, is it the output power of the EMI filter alone, or the entire system you are using the filter for? Great video btw! Thanks a lot!!!!!
@RGBEngineering Ай бұрын
So the output power was just an example I used. The important thing is to make sure your filter can handle the amount of current (both RMS and peak).
@umair7561 Ай бұрын
Hey, I am going though transistor concepts. Why does pnp base need to be set 12v to be in cuffoff and why it doesn't work at at 5volts or lower?
@RGBEngineering Ай бұрын
Remember that BJT transistors are current-controlled, so what really matters is the current flowing through them, not necessarily the voltage being applied. The reason it wouldn't work with 5V is because 5V cannot generate as much current as 12V can.

i prefer panel mounted connectors. I've found that PCB mounted connectors cause problems down the road. The repetitive plugging/unplugging tends to crack the solder connections on the PCB possibly even cracking the PCB. Also, assuming this project is going in a project box, why not use a connector that has the power input, power switch or even a fuse holder in one convenient package.

The changes in current can be approximately linear, right? I think an LRC circuit will always produce a logarithmic current curve, it would be more pronounced if for example the duty cycle switching freq. was too slow.

I want an explanation from a programmer's viewpoint; why use an MPU over an MCU? I've only ever programmed bare metal on MCUs and am trying to get to understand where an MPU would be useful. A chip with a full OS just seems like a ton of overkill. What type of projects need that kind of computing power?
@kenengel620 2 ай бұрын
For example, I see a lot of audio based projects (.mp3, .wav, etc.) that use an MPU; however, I'd think that a 32-bit MCU should be able to handle it. Am I wrong?

Hi. Can someone help please. I have a 24 inch Apple Cinema Display that has stopped receiving a video signal from my MacBook. The all in one cable that has failed is no longer made and I cannot find a replacement anywhere. I have read that I can wrap my cable in foil or a self adhesive foil tape and if I fully shield the cable with the foil then it will create a new shielding. Would this work? I have nothing to lose as without the cable then the display is good for parts only. Would I also have to create a new layer of insulation over the top of the newly created shielding? Thanks for any advice.

Thank You for this video. I have a question about protecting an Arduino Nano 33 BLE. This board operates from 7V to 21V. My intention is to use it for Automotive applications < 15V. I have been considering the Littelfuse model TP6KE18CA. My concern is the max clamping voltage of 25.2V of this TVS diode is greater than the max 21V operating voltage of the Arduino. All other parameters appear to be OK with reverse standoff at 15.3V and breakdown voltage of 17.1 to 18.9. Is this a concern?
@shanefrank3281 5 ай бұрын
This is a very helpful video. Many designs I have seen just seem to randomly have a TVS with the VRWM just about the signal level thrown on the input. In the case of an op amp with max +/-13V rails and an input signal that is +/-10V, if you select a TVS with VRWM of 11V, the Vclamp will often be 19V or more and VBR might be >13V. So before this TVS starts conducting much current, the input pad protection of the op amp will forward bias and conduct current to the 13V supply. But those often do not have much current carrying capability. So am I correct in saying that a TVS diode can't be used in this situation? I guess you could use the diode array like you mention in your video. Would it also be acceptable to have use a TVS diode with a resistor in series with the input of the op amp? If Vclamp was 19V for the TVS and the input pad protection diodes started conducting at 13.7V and could handle no more than 10mA, then you could size the series resistor to be larger than (19-13.7)/10mA = 530 ohms. Would this work?
