12V 1A SMPS Power Supply Circuit Design

In this tutorial we will cover 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.

Flyback Converter Circuit

In electronics, a regulator is a device or mechanism which can regulate the power output constantly. There are different kinds of regulators available in the power supply domain. But mainly, in the case of DC to DC conversion, there are two types of regulators available: Linear or Switching.

DIY Breadboard Power Supply Circuit on PCB

A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a simple module. Most of the digital circuits or embedded circuits have a standard operating voltage of either 5V or 3.3V, so I decided to build a Power supply which can supply 5V/3.3V on the power rails of the breadboard and fits snugly on the breadboard.

10A Step-Down DC/DC Converter:

Step-down DC-to-DC converter also known as “buck converter” is a power converter, which lowers down the voltage coming from the input source to the load while rising up or maintaining its current rating. The reference design is a 10A step-down converter, which features ISL8200AM from Intersil. Th…
