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 […]

220V AC to DC Voltage Converter Circuit
This 220V AC to DC Voltage Converter is small circuit like small adapter for our devices. Wall socket gives AC power but many electronics like phone, laptop, LED light they need DC power to work; hence, this circuit work like translator, it take big AC power from wall and change it to smooth DC power […]
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 […]
Simple 3 Ampere Adjustable Power Supply Circuit using IC LM350
Think Simple 3 Ampere Adjustable Power Supply Circuit using IC LM350 is like super cool power adapter for our electronics project. Also, this circuit uses one chip called LM350 it is strong and give very good power, as tt can give power up to 3 amp and voltage we can change from 1.25V to 25V. […]
DC to DC Adjustable Converter Circuit using IC TL497A
This DC to DC Adjustable Converter Circuit using IC TL497A works like small helper which can change voltage from power source. Also, it takes a low input voltage and produces a higher output voltage, much like a small power adapter, furthermore, we can modify this circuit to operate in different ways, depending on the output […]
