MPQ4433GL-P voltage regulator working principle

The MPQ4433GL-P voltage regulator is a DC-DC switching converter that operates in a Fixed-Frequency, Pulse Width Modulated(PWM) mode. In this mode, the regulator cycles the switching transistor between an on and off state at a fixed frequency; the width of the pulses is varied to control the output voltage. This technology also employs current-mode control, which allows it to provide excellent load and line regulation, fast transient response and low output ripple.

The starting sequence of the controller is always the same regardless of the input voltage. First, the power up circuit supplies power to the IC, then the PWM circuit triggers the oscillator, which begins to produce pulses that are sent to the power switch. The power switch then begins to cycle at the predetermined frequency, enabling the output voltage to rise. During operation, the PWM circuit adjusts the pulse width of the signal sent to the power switch, causing the output voltage to be regulated. When the output voltage reaches its desired level, the PWM circuit sends the signal to the power switch to turn off.

The operational control is done by a current sensing element that enables the current-mode control operation and allows the controller to recognize the difference between the desired and the actual output current. When these two values are not equal, the controller adjusts the pulse width of the signal sent to the power switch to adjust the output voltage.

The overvoltage protection (OVP) circuit is also activated when the output voltage exceeds the device’s maximum programmed value. This prevents the device from damage in overvoltage conditions. Furthermore, this voltage regulator is also thermally protected, making it suitable for applications where the operating temperature may become too high. This allows the device to shut down before it is damaged by excessive heat.
