In this project we are going to step down 12 V DC to any DC value between 2 and 11 V. The circuit which steps down the DC voltage is known as buck converter. The output voltage or step down voltage needed is controlled using a potentiometer connected to Arduino. By Ankit Negi INTRODUCTION TO […]

Smart Buck-Boost MPPT Solar Charger Circuit for 12V 24V Battery
In this post we are going to learn how we can make one real working smart solar battery charger circuit which can do MPPT charging. We are using Arduino Nano as the brain for controlling everything. We will also use INA219 sensor module so that we can read the solar voltage and current properly. And […]
How Buck Converters Work
The article below presents a comprehensive know how regarding how buck converters work. As the name suggests, a buck converter is designed to oppose or restrict an input current causing an output that may be much lower than the supplied input. In other words it can be considered a step down converter which could be […]
5V, 12V Buck Converter Circuit SMPS 220V
This step down buck converter will convert a 220V AC input from mains supply to 5V or 12V or 24V DC with 90% efficiency. The proposed buck converter is an SMPS circuit using the IC VIPer12A from STMicroelectronics. The circuit uses negligible number of external components yet is able to operate directly from mains AC input. The Buck […]
DC to DC Converter Circuits using SG3524 [Buck, Boost Designs]
A DC to DC converter is basically a switch-mode power supply, designed to work either as a boost-converter to step-up a low voltage DC to a higher voltage DC, or as a buck-converter to step-down a higher voltage DC to a lower voltage DC. The switched mode conversion ensures that the power transfer in the […]
Adjustable 1.2V to100V DC Buck Converter Circuit using LM5164
Ok now we have this LM5164 chip, and we want to drop voltage from 100V down to let’s say 12V, right? But we also need 1A output so we need to design everything properly. Now this chip is cool because it has ultra-low quiescent current (IQ) so it does not waste much power when it […]
