    بھت اچھا سر، ایسی ویڈیو مجھے ابھی تک کہی نہی ملی، میرے پاس کچھ یو پی ایس پڑھے تھے جو کہ چارجنگ کے مسلے تھے اور اس پے بھت کام کیا لیکن ٹھیک نہی ہو رہے تھے، جیسا ہی اپ کا ئ ویڈیو دیکھا تو وہ یو پی ایس اٹھایا اور icکو اسی طرخ چیک کیا جو کہ ic کے pin 4 پر voltage زیرو تھا جس پے ایکsmd ٹرانزسٹر لگا تھا جو کہ اپنا کام نھی کرتا تھا، تو replace کر کے ok ہو گیا،
    بہت بہت شکریا سر،👍🏽

    Sir you are so thorough and you explain the theory and practical very accurately and one can follow your explanation very easily. My most sincere thanks to you and am sure lot many people shall benefit from your knowledge transfer.
    Please clarify does PWM IC SG6848TZ1 also can be tested similarly or not.
    Please include different IC Nos used for similar function so it can be good for reference and replacements if required.

    hello sir, i am using uc3845 for designing a smps. the output is 24v 2.5a. i am confused about the auxiliary voltage and current. i am suggested that "auxiliary voltage are calculated based on the PWM IC's UVLO upper limit (Overload Protection) voltage value at the maximum power output of the converter". still, I am illiterate about this topic. can you please explain and guide me?

    Mujhe ye nhi samjh aa raha he ke

      But supply is working good at 500mA.
      Where is ampere capacity ?? Of supply because it is 6A capacity if it goes to work over than 500mA it is get started blinking.
