The Voltage Booster Circuit plays an important role in many power applications that require more power than it can deliver. The NE555 boost circuit is a good boost circuit. This circuit uses the NE555 IC, a frequency converter or oscillator, to step up the voltage from the DC input to a higher DC output. In this article, we will explore how the power supply works and get into the details, pin configuration and specifications of the NE555 IC. Additionally, we will demonstrate the benefits and uses of boosters, demonstrating their importance in a variety of electrical applications.

Components reqired:

  1. NE555 IC
  2. 10K Variable Resistor
  3. BD139 Transistor
  4. IN4007 Diode
  5. 100 nf Capacitor
  6. 22uf Capacitor

NE555 IC: The NE555 IC is the basis of the power circuit, also known as the 555 timer IC. These highly reliable and cost-effective integrated circuits combine 23 transistors, 2 diodes and 16 resistors in an 8-pin package. Operating over a wide voltage range, the NE555 can generate precise timing signals from microseconds to timer timings using resistors and capacitors. Its versatility makes it a popular choice for pulse generation, delay circuits, frequency design and pulse width modulation (PWM) applications.

Pin Configuration of NE555 IC: Understanding the pin configuration of the NE555 IC is crucial for setting up and maintaining uptime. 8 pins are reserved for the IC to perform many functions:

  1. GND (Ground): Used as a power connection.
  2. TRIG (Trigger): Start timing loop, follow input pin.
  3. OUT (output): Generates timing signals as output pins.
  4. RESET: Stop or reset the timer with a reset.
  5. CTRL (Control Voltage): Use external voltage to set threshold and level.
  6. THR (Threshold): The duration of the timer is determined by the threshold.
  7. DIS (Discharge): Removes the timer from the output pin.
  8. VCC (Positive Supply Voltage): Provides positive supply voltage.

BD139 Transistor: BD139 is a popular NPN bipolar junction transistor (BJT) widely used in electronic circuits. Designed for general purpose amplifier and switching applications. The transistor is in the TO-126 package for easy mounting on the printed circuit board. With a maximum collector current of 1.5 amps, the BD139 can handle high power levels. It is rated at 80 volts and is suitable for low to medium power applications. The transistor exhibits high efficiency and low noise performance, making it suitable for audio amplifier circuits and signal amplification work.

Booster Circuits:


Advantages:

  1. Boost Voltage: Boosters can use lower voltage sources.
  2. Efficiency: Modern amplifiers are designed for high efficiency, which reduces power loss during voltage changes.
  3. Compact size: Advances in semiconductor technology make electronics suitable for portable devices and limited space.
  4. Voltage Regulation: Booster circuits often have a voltage regulation mechanism to maintain a stable and constant voltage even when  the input voltage is variable.

Application:

  1. Power Supply Function: Booster to extend battery life or use low voltage battery for devices that need more voltage.
  2. Electric Power Boosters: Boosters increase the low power output of solar panels or wind turbines for efficient power distribution and integration.
  3. Automotive Electronics: Install power sensors, LED lighting and audio systems in automotive systems.
  4. Communication: Boosters provide a constant voltage value for communication equipment to ensure stable operation and lighting.

Conclusion:

The NE555 boost circuit powered by the NE555 IC provides a good solution for boosting voltage levels in electronic applications. With its design, high performance and versatility, the NE555 IC becomes the basis of power amplifier design. The benefits of support such as increased voltage, efficiency and voltage control make it invaluable in everything from portable devices to renewable energy systems and automotive electronics. Generators can operate efficiently by harnessing the power of energy, providing efficiency and reliability.
