Working Principle of the MC33063APG4

The MC33063APG4 voltage regulator works on the principle of a switched-mode power supply. The device is designed to have a fast transient response and a low-output voltage ripple. It has high-side, low-side, and output diode protection, along with internal current limit and over-temperature shutdown circuits.

The device operates in current-mode, and its working is based on a voltage signal representing the output current. A current sense input is connected to the output voltage of the power switch and determines the peak switch current.

The device uses this signal to set the on-time of the power switch. The output voltage is monitored continuously and feedback from it is used to modulate the on-time of the power switch. This on-time is then set precisely by the error amplifier and the reference voltage.

The oscillator and the error amplifier setup the frequency, the voltage level and the compensation of the power switch. The device can be synchronized to an external clock signal. The current sensing input provides protection to the device when the power switch current is too large.
