In this tutorial we will learn how to build a 12v smps circuit that would convert ac mains power to 12v dc with a maximum current rating of 1 25a. Dc12v 2a power supply adapter sansun ac100 240v to dc12v transformers switching power supply for 12v led strip lights 12 volt 2 amp power adaptor 2 1mm x 5 5mm us plug 1pcs 4 5 out of 5 stars 3 014. The central ic is lm7812 which will change over the voltage starting from the transformer and gives a 12v controlled output on pin 1 of the lm7805 ic. First power supply circuit is built with bd139 one zener diode and a few passive components.
