Many electronic circuits require a stable 5V supply, but the input voltage is not always constant; it may be 12V or rise to 30V, so a buck converter reduces the input voltage to a stable 5 V output. This 5V High Current Buck Converter Circuit using IC MC34063 reduces voltage efficiently and it also saves […]
5V USB to 1.5V or 3V DC Converter Circuit
Today, many small devices need low voltage for example 1.5V or 3V. A USB port provides a 5V output, so this circuit uses a buck converter to reduce the voltage to 1.5 V or 3 V. The MC34063 IC controls the conversion, making the circuit low cost, easy to build, reliable, and efficient; the IC […]
12V to 5V Buck Converter Circuit using Transistors
In todays world power supply plays a very important role, because most electronics need stable 5V DC; but sometimes if the input voltage is high like for example 12V battery or adapter, then we must reduce voltage safely. Therefore, this buck converter reduces the voltage with high efficiency and this 12V to 5V Buck Converter […]
IC 7805 12V To 5V 2A Boost Converter Circuit
Sometimes 7805 regulator is not enough, as it gives only around 1 amp current; however, many projects need more current for example motors, relays, LED strips and logic boards together. Therefore, we need a simple solution, so we used an external power transistor TIP42 with 7805 IC, as this transistor boosts output current with this […]
IC LM309 Based 5 Volt Power Supply Circuit
Today, many electronic circuits require a stable 5V DC supply; however, the AC mains voltage is much higher, so the circuit must reduce the voltage before converting it to DC. Furthermore, voltage regulation is important, so this circuit uses a voltage regulator, also this article explains about simple IC LM309-based 5V power supply circuit. Moreover, […]
5V 0.5A Regulated Power Supply Circuit
Power supply is the heart of any electronic circuit, without stable voltage the circuit will fail; sometimes 7805 IC is not enough and also sometimes current requirement is higher, therefore, discrete regulator is useful. This 5V 0.5A Regulated Power Supply Circuit gives 5V output at 0.5A current and it uses TIP3055 transistor and IC TL431 […]
