Switching power supplies are different from linear power supplies, switching power supplies utilize switching transistors mostly in the fully open mode (saturation area) and fully closed mode (cut-off area) switching between the two modes are characterized by low dissipation, switching between the conversion will have a higher dissipation, but the time is very short, so more energy saving, less waste heat. Ideally, the switching power supply itself does not consume power. Voltage regulation is achieved by adjusting the on and off times of the transistors. On the other hand, in a linear power supply, the transistors operate in the amplification region during the generation of the output voltage, which itself consumes power.
