[24] How LED driver works (stepdown converter)

Unfortunely video No.23 hasn't been released yet because my phone doesn't have enough storage to edit it
PS: Video No.23 is the video where I repair this lamp
Sayang sekali video No.23 masih belum dirilis karena saya ga punya cukup penyimpanan di HP saya untuk edit videonya
NB: Di video No.23 saya memperbaiki lampu ini
And yes I know this is quite simplified explanation of how stepdown (buck) converter works
