Working Principle

The VI-262-EY-F1 operates on the principle of switching power converters. The device consists of a two-stage power conversion process which begins with an oscillator controlling the switching of MOSFETs. These MOSFETs then control the current flow through an inductor. The inductor stores the current and releases it as the current drops, which regulates the output voltage. The output voltage is then regulated using the control circuit and the protection circuit.The oscillator is responsible for controlling the MOSFETs. It creates a switching frequency which is determined by the magnitude of the input voltage. This switching frequency is then maintained at the same level regardless of the input voltage or load. The MOSFETs are then used to control the flow of current through the inductor. The inductor acts like a capacitor and stores the current. As the current drops, the stored energy is released, which regulates the output voltage.The control circuit is responsible for maintaining the output voltage and ensuring that it stays within the specified range. The protection circuit is used to protect the device from excessive current flow. It prevents the device from being damaged by over-current conditions.

Conclusion

The VI-262-EY-F1 is an efficient two-stage DC-DC converter. Its wide input voltage range and high output current capability make it suitable for a variety of applications. Its surface mount design, adjustable output current limit, and protection circuit help ensure that it operates correctly and safely. The device works on the principle of switching power converters and consists of an oscillator, MOSFETs, an inductor, a control circuit, and a protection circuit.
