VE-25V-EY-F3

DC-DC converters are widely used in today\'s electronics industry. They are used in numerous applications ranging from consumer electronics to industrial and military applications. The VE-25V-EY-F3 converter is an example of these converters. This section will provide an overview of the VE-25V-EY-F3 application field and working principle.

The VE-25V-EY-F3 DC-DC converter is a voltage step-down converter. It is a circuit topology with buck design for converting a higher voltage level to a lower voltage level, while still providing the same amount of power. This buck converter integrates four power MOSFET switches, a full bridge, and a control circuit into a single package. It provides excellent efficiency with integrated auto shutdown control and energy saving modes. This converter is designed to operate in a wide range of input voltage between 8 to 25Vdc with an output voltage ranging from 0.8 to 20Vdc. It is popularly used in power supply applications such as personal computers, laptops and LED displays.

Working principle of the VE-25V-EY-F3 converter is as follows. In the Steady-State mode, the input voltage is used to charge an Inductor L1 via MOSFET S2 and braking diode D1. As soon as the voltage in the inductor reaches the peak value, the MOSFET S2 is switched off. This turns the diode D2 ON and the energy stored in the inductor is released into the load. The ON/OFF duty cycle of MOSFET S2 controls the output voltage. The average value of the output current is obtained by controlling the duty cycle of the MOSFET S2.

The VE-25V-EY-F3 converter is also equipped with an Auto Shutdown control circuit, which enables the converter to enter an idle mode when not in use. This helps to save energy and reduce power consumption. The integrated auto shutdown control circuit is also designed to protect the converter from overload or overheating by shutting down the converter when detecting abnormal output conditions.

In summary, the VE-25V-EY-F3 DC-DC converter is a versatile and reliable voltage step-down converter designed for a wide range of applications. The onboard power MOSFET switches and full bridge integrate together to provide excellent efficiency with auto shutdown and energy saving modes. The converter works on the principle of controlling the duty cycle of the MOSFET switch to enable the device to produce the desired output. The integrated auto shutdown control circuit helps to protect the converter from overload or overheating while also saving energy.
