VTD48EF240T012A00 is a power supply module belonging to the family of Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS. It is a single-phase 12V input, 240W output voltage module. Its structure is very compact, and its size is only 144mm x 74mm x 20mm. It is suitable for a wide range of application scenarios, including consumer electronics, security systems, medical equipment, industrial automation, and various control systems.

VTD48EF240T012A00 power supply module has several advantages. Firstly, it has universal input of 85VAC-265VAC, which meets the needs of different application scenarios. Secondly, high efficiency of up to 90% enables the device to operate in different environmental conditions with high efficiency. Thirdly, it has a soft start function, which enables the device to turn on and off without impacting the power supply source. Lastly, the module has overvoltage and overcurrent protection, which makes it suitable for use in various environments.

The working principle of this evaluation board power supply module is based on a traditional switching power supply topology. The power supply module takes the incoming AC voltage and converts it to a DC voltage through a rectification process. The output voltage is then regulated by a switching transistor, and the feedback signal is generated by a zener diode. This feedback signal is used to turn on and off the transistor in order to maintain a stable output voltage. At the same time, the output is further regulated by an external power factor controller (PFC). The use of a PFC helps to reduce line-frequency interference and improve efficiency.

The VTD48EF240T012A00 power supply module has a wide range of applications, such as consumer electronics, medical equipment, security systems, industrial automation and various control systems. It is suitable for a wide range of applications due to its high efficiency, wide input range, and its compatibility with multiple regulatory standards (such as UL/ETL/CE/GS/SEMKO). Also, its integrated protection functions make it suitable for various harsh environments.
