Transformer less Power supply || LED driver power supply
Hi in this video lectures you will learn non isolated transformer less Power supply design.
This supply is rated for 12volt 140mA and it is made using single chip. it is very efficient and can be use with wide range of input supply voltage.
it is basically use for led drivers. on your demand I will provide it's Gerber file for PCB making. you can contact me via emails or telegram given on home page of my channel.
