Working Principles

The MC33063ADRJR operates as a switching regulator, utilizing pulse-width modulation (PWM) to regulate the output voltage. It consists of an oscillator, error amplifier, voltage reference, comparator, and power switch. The input voltage is switched on and off rapidly by the power switch, creating a square wave. This square wave is then filtered and fed into the error amplifier, which compares it to the desired output voltage. Based on this comparison, the duty cycle of the square wave is adjusted to maintain the desired output voltage.
