VE-B6H-EY-F1

DC-DC converters are devices that convert direct currents from one voltage level to another, providing power to various equipment with different power requirements. The VE-B6H-EY-F1 DC-DC converter is a high-performance, isolated half-bridge converter that provides up to 200W output power with a switching frequency of up to 500kHz. Its wide input range, high efficiency, and high power density make it ideal for use in many applications.

Application Field
The VE-B6H-EY-F1 DC-DC converter is suitable for various applications such as industrial and consumer electronics, renewable energy systems, medical equipment, aerospace and defense systems, automotive systems, LED lighting, telecom systems, and wireless applications. It is designed to provide a reliable high-power output, and is suitable for a wide range of input voltages and frequencies.

Working Principle
The VE-B6H-EY-F1 DC-DC converter is based on a flyback topology, in which the energy stored in the transformer primary is used to provide the output current. It operates in an isolated half-bridge isolation configuration where the primary side is connected to the input voltage, while the secondary side is connected to the output voltage. The transistors on the primary side are driven in a toggle mode, switching on for a certain time and then switching off. During the ‘on’ period, energy is transferred from the primary to the secondary through the transformer, providing the output current. During the ‘off’ period, the transformer primary side returns to its original state and the energy is returned to the input source. This cycle is repeated in order to maintain the output voltage.

The converter also features a number of protective features such as short circuit protection, overvoltage protection, and thermal protection. It also features synchronous rectification to reduce losses and improve efficiency. The synchronous rectification eliminates the need for a secondary diode, resulting in reduced power losses. The wide operating temperature range of -40°C to +85°C ensures the converter can work reliably in harsh and extreme environments.

In addition to the above features, the VE-B6H-EY-F1 DC-DC converter is also equipped with a built-in over-temperature protection and over-current protection. The over-current protection can detect when the output current has exceeded the set limit and will shut off the converter to prevent damage. The over-temperature protection monitors the internal temperatures and will shut off the converter if the temperature exceeds a certain limit. The converter also features a soft start function to reduce in-rush current on start-up.

The VE-B6H-EY-F1 DC-DC converter is a versatile and reliable solution for a wide range of applications. Its wide input range, high efficiency, and high power density make it ideal for use in many applications. Its built-in protections ensure high reliability and safety even in extreme working conditions.
