Simple Buck Converter Circuit for Converting 12V to 3V also called step-down converter is common in electronics; it takes high DC voltage and makes it lower, like a valve but for voltage. Additionally, phones and laptops use this type of circuit to convert a 12V battery supply into lower voltages, such as 3V, for smaller […]

How to Convert 5V to 3.3V Circuit
Have anyone tried using a toy which needs 3.3V but charger gives only 5V? that is too much power! This article for How to Convert 5V to 3.3V Circuit is like small helper, which take strong 5V and make it weak 3.3V which is right for device. Furthermore, this circuit help when USB or charger […]
Simple Boost Converter Circuit from 3V to 5V
To change 3V to 5V we need to use a boost converter, as this Simple Boost Converter Circuit from 3V to 5V take low voltage and make it higher. Also, it takes 3V from battery and give 5V to run our devices. Circuit Working: Parts List: Components Values Quantity Resistors (All resistors are 1/4 watt […]
Adjustable Power Supply Circuit using IC TDA2030
This Adjustable Power Supply Circuit using IC TDA2030 can change the voltage it uses small trick which is little bit surprising; because the chip TDA2030 is normally for making speaker sound loud and can also work like voltage controller. With smart circuit design it gives steady DC voltage and we can change output which is […]
How to Increase Voltage Output of 7812,7805 ICs
It is useful to understand How to Increase Voltage Output of 7812,7805 ICs, but this approach is not always a good idea. These ICs provide fixed output voltages by design, with the 7812 producing 12 V and the 7805 producing 5 V. Better way is this: if we want other voltage just buy other voltage […]
Variable Power Supply Circuit using 7805 or 7812 ICs
This Variable Power Supply Circuit using 7805 or 7812 ICs work like smart adapter; it uses chip like 7805 or 7812 which normally gives 5V or 12V and add some other parts like resistor and turning knob like potentiometer. Hence, these extra parts help change the voltage up or down so we can set what […]
