The quantity of current that flows to a load, or the item being powered, is controlled by a current limiting circuit that uses an LM317 or LM338 integrated circuit. By carefully configuring these integrated circuits, voltage regulators can also function as current limiters. An input voltage Vin from a power source enters the circuit. Three […]

Simple Boost Converter Circuit using IC 555
A basic design that steps up a low voltage DC input to a higher voltage DC output is a boost converter circuit that uses the IC 555 integrated circuit. Here, the circuits central component IC 555 produces a pulse width modulated PWM signal that regulates the other components switching. Additional parts utilized in this post […]
12V SMPS Driver Circuit for LED Strip
A 12V SMPS Switch Mode Power Supply Driver Circuit is a regulated power source that transforms mains power which is typically 110V or 220V AC, into a steady and secure 12V DC voltage that may be used to light LED strips. We will construct a simple, reasonably priced and potent LED driver circuit in this […]
Simple Non-Contact 220V AC Detector Circuit using IC 555
It might be dangerous to tamper with electrical cables, particularly if you are unfamiliar with electronics, if not used properly electricity may be hazardous. Therefore, being secure is crucial! to prevent injury, you should determine whether there is any residual electricity (leakage voltage) before handling electrical lines. Using a IC 555 chip and other common […]
3V to 9V Dual Power Supply Circuit
An IC 555 is used in a reasonably simple circuit to provide both positive and negative voltage outputs from a single 3V source, such as two AA batteries in a 3V to 9V dual power supply circuit. The 555 IC set up as an astable multivibrator is used in the circuit. This indicates that it […]
Simple Voltage Follower Circuit using Op-amp IC 741
The operational amplifier (op-amp) in a voltage follower circuit produces an output voltage that precisely follows the input voltage. It is also referred to as a buffer amplifier or unity gain amplifier. Because of its price and adaptability, the IC 741 is a popular option for op amp. The high input impedance and low output […]
