Hello Everyone
I need a power supply without transformer (12V 3W)(Vin:220V AC 50Hz, Vout: 9-15VDC). My circuit should be small size. I was searching about that design for a while. I tried LNK306 but it is not very good in my opinion. I couldn't get a quality voltage level with it.
Also i tried some of big capacitor and resistor circuits. But with that u have to use big capacitors and they are expensive and huge size. So i need some help about that.
Is anyone know anything about with this circuit? Please help me, thanks..
