The working principle of the DCM3623E50M13C2M00 is based on the convertor circuit shown in the following diagram. The circuit features an active MOSFET high side switch that acts as a switching regulator. This switch is driven by an internal oscillator, and a power conversion IC. The current flows through the inductor, converting the AC waveform to a low-voltage DC signal which is supplied to the output. The switching is controlled by the PWM signal from the control circuit. The output voltage is regulated by an internal voltage reference.

The circuit also features a full wave bridge rectifier, a capacitor for filtering and for supplying power to the internal logic, as well as a separate rectifier for the output voltage. The feedback voltage is monitored by an internal voltage reference and the PWM frequency is internally set. This device also features active current-limit protection and temperature shutdown.

The DCM3623E50M13C2M00 is an efficient all-in-one solution for applications requiring high efficiency, cost effectiveness, and small size. It integrates all the components necessary for a non-isolated DC/DC converter in one package. Its wide input voltage and temperature ranges, as well as its integrated protection and filtering circuitry make it the ideal solution for a variety of applications.
