In this post we comprehensively discuss how to construct 12V 5 Amp SMPS circuit using MOSFET and optocoupler feedback. Its efficiency is around 85%. What is a 12V 5 Amp SMPS Circuit: A 12V 5A SMPS Switched Mode Power Supply circuit is designed to provide a stable and regulated 12V DC output with a maximum […]
Simple 14V SMPS Circuit
I built a new power supply that can give out 14V at 1 amp. It is flexible and can be used for many things. I use it to give extra juice to some electronic parts. This new design is very similar to a power supply I made before 3.3V at 2.5 amps, so I wont […]
Simple 3.3V 3Amp SMPS Circuit
In this post we will learn how to build a simple 3.3V 3 Amp SMPS circuit which can be used for powering all types of microcontroller and digital electronics circuits efficiently. The main advantage of this SMPS circuit is that it does not dissipate heat unlike linear regulators which generates a lot of heat and […]
Simple 5V 1A SMPS Circuit
I tried to build a simple power supply that changes AC current to 5V at 1 amp. I used a tiny chip called the TNY267P. This chip is like a whole mini system for a power supply, it controls the current, turns it on and off, protects itself from overheating and even gets its own […]
Li-ion Battery Charger Circuit Using LTC4056 IC
This guide explains how to build a charger for single lithium-ion (Li-ion) batteries. It uses a special chip called the LTC4056, which can both limit the charging current and stop charging at the right voltage. This chip only needs a few other parts to work well. We will provide instructions and details on how to […]
Simple Solar Battery Charger Circuit
This guide will show you how to build a charger that uses sunlight to charge a 12V battery, like the ones in cars or some toys. Normal chargers need an outlet, but this one uses a solar panel instead, so it is great for places without electricity. We will call this charger a “Solar Power […]
