Working Principle

DE03D0505A utilizes a synchronous rectification switch mode power supply topology with an input voltage range of 5 to 24 volts. The module is composed of an input stage, an output stage, a control circuit, and a closed loop that controls the output voltage. The input stage consists of a rectifier bridge to convert AC mains to DC, and an input filter capacitor to remove any residual AC components from the output. The output stage consists of an active switch, a synchronous rectifier, an output filter, and a feedback circuit. The active switch is a power MOSFET that is controlled by the control circuit. The synchronous rectifier is composed of a body diode and a freewheeling diode, which are used to prevent short-circuit current and minimize switching losses. The control circuit monitors the output voltage and adjusts the duty cycle of the switch accordingly to regulate the output voltage.

In summary, DE03D0505A is a highly efficient, cost-effective solution for a wide range of applications. It can be used in industrial, automotive, consumer and portable electronic applications, as well as in renewable energy and mobile power systems. It utilizes a synchronous rectification switch mode power supply topology, with an input voltage range of 5 to 24 volts. The module consists of an input stage, an output stage, a control circuit, and a closed loop that controls the output voltage.
