A Brief Overview of 12V 1A SMPS Circuit:
Every Electronic device or product requires a reliable power supply unit (PSU) to operate it. Almost all devices in our home, like TV, Printer, Music Player etc. consists of a power supply unit built into it which converts the AC mains voltage to a suitable level of DC voltage for them to operate. The most commonly used of type of power supply circuit is the SMPS (Switching Mode Power Supply), you can easily find this type of circuits in your 12V adapter or Mobile/Laptop charger. 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. This circuit can be used to power small loads or even be adapted into a charger to charge you lead-acid and lithium batteries.
