The MC34063ADR is a monolithic integrated voltage regulator circuit which offers the designer a cost effective solution to his requirement for an efficient, low cost, switch mode voltage regulator. As with any other switch mode power supply, the MC34063ADR operates by cycling a series of switch elements in the power stage to produce its output voltage. The device has the ability to operate in two different modes, the fixed frequency mode and the variable frequency mode. The operation of the device can be varied depending on the specific application. In this article we will discuss the application field and working principle of the MC34063ADR.

Application Field

The MC34063ADR can be used in a wide variety of applications, such as:

  • Battery operated systems
  • DC-DC converters
  • DC motor controllers
  • Lighting controls
  • General pulse width modulation (PWM) control

Working Principle

The MC34063ADR is an integrated circuit (IC) that has been designed to operate as a switching regulator in either fixed frequency or variable frequency modes. The device is controlled by two external input signals: the Enable pin, which is used to turn the device on and off, and the Control pin, which is used to control the frequency and/or the current of the device.

When the Enable pin is asserted, the MC34063ADR is put into its ‘ON’ state, and current will begin to flow through the device. The frequency at which the switching occurs is determined by the value of the Control pin. For a fixed mode MC34063ADR, the Control pin is connected to a capacitor with a constant value. The capacitor and the frequency control the switching frequency of the device, which is typically set to 25 kHz. For a variable frequency application, the Control pin is connected to a voltage divider network, allowing varying of the frequency to meet certain demands.

The MC34063ADR can be used to generate a step-up, step-down, or inverting converter. The device is also capable of operating in either a continuous mode or in a burst mode. In continuous mode the PWM signal will be fed to the load constantly, while in burst mode the duty cycle of the PWM signal will change, allowing for changes in the output voltage.

Once the frequency, duty cycle, and mode are determined, the MC34063ADR can be wired up in the appropriate topology needed for the specific application. The device will then have the ability to step up, step down, or invert an input DC voltage to produce the desired output. The device can produce output voltages ranging from 1.25V up to 75V, depending on the application.

Conclusion

The MC34063ADR is a versatile monolithic IC that can be used to provide an extremely cost effective solution for many switching regulator applications. It is capable of operating in either fixed frequency or variable frequency modes, and can be used to generate step-up, step-down, or inverting converters. The device can be used in battery operated systems, DC-DC converters, DC motor controllers, lighting controls, general pulse width modulation (PWM) control, and a variety of other applications.
