DC DC Converters

A DC DC converter is a device used to convert the voltage of a battery-powered device from direct current (DC) to a different level of direct current (DC). Commonly found in electronic devices, DC-to-DC converters are used in consumer applications such as laptop power supplies, portable electronic device chargers, and auxiliary power supplies to convert the available voltage of a battery to a level appropriate to run the device.

The VE-20J-MY-F2 is an example of a DC-DC converter. This model is a single input isolated DC-DC converter. It is composed of a non-isolated DC-DC buck converter that produces a regulated output voltage and an isolated DC-DC flyback converter with the same output voltage as the buck converter.

Applications

The VE-20J-MY-F2 is typically used in telecommunication, industrial control, lighting, and power supplies for computer-related peripherals such as monitors, sound cards, and printers. It is suitable for low power applications up to 10W since it offers an isolated DC output voltage of 3.3V up to 10V and a maximum output current of 2A.

Working Principle

The operating principle of the VE-20J-MY-F2 DC-DC converter involves the use of two inductors and two capacitors. The first inductor is used to store energy in the form of a magnetic field while the second is used to return the energy stored in the first inductor back to the input. The two capacitors are used to filter the output voltage to provide a smooth DC output voltage. The output voltage is regulated by the use of pulse width modulation (PWM).

The VE-20J-MY-F2 is a cost effective, high efficiency solution for converting an input voltage to a smaller, isolated output voltage. It has a high switching frequency of up to 250kHz, allowing for a very fast response time. It is also SELV (Safety Extra Low Voltage) compliant, enabling engineers to achieve their performance objectives without compromising safety.

Conclusion

The VE-20J-MY-F2 DC-DC converter is an effective, efficient, and safe solution for low power applications up to 10W. It offers high efficiency, fast response time, and SELV compliance, as well as a high switching frequency of up to 250kHz. This makes the VE-20J-MY-F2 an ideal choice for applications in the telecommunication, industrial control, lighting, and power supply for computer-related peripherals such as monitors, sound cards, and printers.
