Good Day Everyone! I am new here. I am currently a mechanical engineering student who's doing a project involving control systems and regenerative braking. So far my system of parts include a Pressure transducer attached to a foot pedal. When the brakes are applied the pressure transducer will send a

Hi, I have a air conditioner power card, but the chip (TNY) burned. So, I can’t read anymore what is written on it. How can I know the exact reference of my chip? I found a poor quality picture on the internet, on which I can read « K347 »

Dear all. We have a doubt with one of our design. We have our own opinion but we would like to know yours. We have the AC/DC design attached. It is a LinkSwitch-TN2 to build a AC/DC converter from three phase (85-265 AC) to 12Vdc@250mA. We use this design in

HI we have design the SMPS using TNY287K . The voltage range is 85V to 265Vac. but we have following problems here SMPS is turning on 54Vac input itself Output voltges are desinged for +15V,0.075Amp but when i am increasing the input voltage the all output voltages going to >30V

I have one old power board with failed TOP246YN. Contacting manufacturer of the board I found that failing of this element is the most common issue with those of their boards and because currently TOP246YN is out of stock at my distributors, plus is marked as "Not for new designs"

Hello PI Engineers, I need your help with an audible noise problem. I have been struggling to first reduce the 12V ripple (now good) and second reduce the sharp persisting audible noise at various frequencies due to different inductors being used. Please reference the attached PNG file for schematic and

When I reply to the post, the "Forbidden. Email seems to be spammer." dialog box pops up.How to solve this?

Hello, sir. In the application document, the chip current limiting point will change with the load change. In the document, it is introduced that the chip will have three overcurrent points as the load increases, such as 30%, 50%, 100%; As the load is reduced, there are also three overcurrent

Hi, We made a Non isolated 86V/290mA led driver using LYT1604 and it is working fine. IS IT SAFE TO RUN LYT1604 UPTO 25Watts ? We will manage thermal issues. Run the driver inside the lamp enclosure continously for one week and no issues found. Kindly advice. Thanks SDM
