So, recently i have been trying to import IR2110 driver IC for simulation, i found this PSPICE model from the infineon website, i did the following steps, i) open the .lib file of the component in LTspice ii) click on .SUBCKT and "create symbol" option but when i get all the connections right, i...
Hi,
I have been repairing circuit boards for a few years and a plumber friend has come to me in the hope I can fix a few of the faulty boiler boards he has laying around. He tends to send them to ewaste but I'm sure they're easily fixed.
I've searched Google and a few forums but can't seem...
Hello people of "All About of Circuits"!,
I am new to electronics. Been fascinated by it for a while, have studied physics (not Electricity, yet, but its my next unit). I got a multimeter and an Ardist DIY kit for my birthday and I am very excited to start testing, experimenting, and building...
I'm new to electronics and decided to learn something new by trying to put together a small rectifier circuit that converts 24VAC to DC. So I put together a little full-wave rectifier circuit that consists of four diodes and an LED and ran into an issue when I tried to measure the DC output...
I am building the Elenco AM/FM radio kit. And for a static power test it is telling me to connect my equipment ground to circuit ground test point 15 while the circuit is being powered by a 9volt battery. . I’m just pretty confused on what it means by “equipment ground” and what I can do to...
What are the ways to test a switching IC TOP266EG with a multimeter?
I want to check it if it is damaged or not.
Link to the datasheet: https://www.alldatasheet.com/datasheet-pdf/pdf/663154/POWERINT/TOP266EG.html
Here is the DATASHEET picture:
Here is the appearence of IC:
Hi guys,
i need help with my doc. I do have to inspection and assembly PCB board I this is my steps are
1-First, I will make sure the PCB board does not have any damage by visual inspection PCB and see if there is any scratch on the lines that will transfer the power.
2- Check the PCB for...
Hello,
I have to transfer 24 VDC to 21 devices which is 1000 ft apart. Is it possible to transfer 24 VDC to such a long distance?
This 24 VDC is coming from SMPS. Does the current/power rating matter in this case?
And how can I calculate total voltage drop at the end (If there is any)?. All...
Hi all
I need a clarification that i have designed a PCB board which has 4 layers, and no components has only holes with supply and ground.
My board has failed in dielectric test.
1) How much time i can test my board for dielectric test.(1,2,times..infinity??)
2) my conductors are so close...
