Working Principle

The S24SE05004PDFH works according to a regulated buck switching topology which operates in discontinuous condition mode (DCM). It is composed of three stages: power FETs, gate drivers, and the PWM controller.

The PWM controller creates an oscillating signal with a certain frequency. When this signal is high, the power FETs switch on and the incoming DC voltage is connected to the output capacitors. During the low part of the signal, the power FETs switch off and the output capacitor voltage is clamped to the output voltage. The PWM controller adjusts the low and high time ratios of the switching signal to make sure the output voltage is steady even when the input voltage, load or temperature varies. This mechanism is known as voltage regulation.
