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?

このモジュールたまに使いますが、レギュレーターなんですね。どおりで発熱が大きいわけだ。
(流石に放熱パッド 付きのSOP-8では放熱に無理があるような)

これのtype-cバージョンをアリエクで買って使ってる
