Power Supply Circuits

Think Simple 3 Ampere Adjustable Power Supply Circuit using IC LM350 is like super cool power adapter for our electronics project. This circuit uses one chip called LM350 it is strong and give very good power. It can give power up to 3 amp and voltage we can change from 1.25V to 25V. So we […]

This DC to DC Adjustable Converter Circuit using IC TL497A works like small helper which can change voltage from power source. It takes low voltage and gives high voltage back like a small power adapter. Good thing is, this circuit can be changed to work in different way and it depends what voltage we want. […]

3V to 24V Variable Power Supply Circuit is like a Swiss knife. One supply does many things. Turn knob to change voltage from 3V to 24V. Circuit is good for projects needing different voltage. There is no need of many adapters just use this one. Circuit Working: Parts List: Category Component Quantity Resistors 3k 1/4 […]

This Simple 3V to 9V DC Boost Converter Circuit is like a hero for battery. If battery is only 3V like from old remote then this circuit makes it strong by giving it 9V as many device need 9V to work good. So if we only have small battery with low power but still want […]

Simple Solid State Relay (SSR) circuit is like ON/OFF switch but with more better and modern. Not like normal switch with moving parts but this one uses special electronics parts like transistor or triac for turning ON or OFF. It works quietly with no noise and last a long time. It is very good for […]

This 1.5V to 5V Voltage Converter using IC MAX756 works like small power booster for battery. It takes low 1.5V battery like AA battery and makes it higher like 5V. This help for running small electronic things that need 5V for working good. The MAX756 chip is like small hero it help circuit change voltage […]
