有益な動画ありがとうございます。フライバックコンバーターの入力電流と出力電流の関係ですが、Iout = Iin x Np/Ns で決まるのでしょうか。この数式の結果と電力が同じという数式で計算すると(Vp x Ip =Vs x Is)電流の計算値が合わなくなりますが、どちらが正しいのかご教示いただけますと幸いです。
Hi, It's long time since you uploaded this Video.. But i hope you can help me with confirming some info, I want to drive LED with this lp4056h ic from 3v input! Coz it has constant current adjustment option and i Don't have any other adjustable LED driver available this moment, I'm Trying to modify my headlamp, it has 3v 5watt led. I'm using 18650 Battery.. So my input voltage Rang is 3v - 4.2v, Lp4056h ic datasheet says It's input voltage 0.3v - 8v, It'll be possible to use this module or just ic to drive LED?
A very practical problem, China has a market, a very large market, and the internal competition is very serious. In the near future, the same product quality will be exactly the same! Japan should develop high-end products and not produce the same products as China!
