    Please sir as I was following this video, you pointed out switching frequency to drive BOTH GATES OF switching mosfets of VOLTAGE REGULATOR. PLEASE SIR THE FREQUENCY REQUIRED TO DRIVE BOTH GATES OF MOSFETS WE follow THE ONE STATED IN VOLTAGE REGULATOR datasheet.

    • @laptex1377
      @laptex1377  2 года назад

      Yes...it. Depends on datasheet.

    OK sir but my question was is it possible to get output voltage when input PWM frequency is flactuating not stable(it has glitch) . Like in this video case VRM CORE IC WAS NOT SWITCHING PROPERLY BUT was THERE WAS OUTPUT VRM COR VOLTAGE.

    • @laptex1377
      @laptex1377  2 года назад

      If PWM is fluctuating then output will also fluctuate.

    Please sir again I have been following this video, I would like to ask at first before changing the VR CORE IC. Was there an output voltage on VOLTAGE REGULATOR CORE IC though it had PWM glitch.because I want to inquire from you that, IS IT POSSIBLE TO HAVE GOOD VOLTAGE ON OUTPUT SIDE OF INDUCTOR WHEN INPUT SIDE HAS GLITCHES OF PWM. LIKE IN THIS VIDEO CASE YOU UPLOADED.

    • @laptex1377
      @laptex1377  2 года назад

      Yes input of inductor is always having PWM so it's not a problem.

    Please sir I would like to know ,it means fluctuating of frequency caused by faulty VRM PWM IC.its the one which caused both +DUTY AND -DUTY CYCLE TO also fluctuate.Hence No output.JUST BECAUSE I WAS TRYING TO INTERPRET THE LOGIC.Because its Hindi video case study.

BECAUSE I TRIED TO FOLLOW THIS VIDEO TODAY I SAW YOU PRESSING AUTO SET BUTTON ON DSO.
