DC DC Converters: VI-21Y-CY-F2 Application Field and Working Principle

DC-DC converters are devices that convert a direct-current input voltage into a regulated output voltage. The input can be either an AC or DC voltage, and the output is usually DC. They are widely used for powering embedded systems, LED lighting applications, and in many industrial and commercial applications. The VI-21Y-CY-F2 is a DC-DC converter that can provide a highly regulated output voltage from an input voltage of 4.5V to 36V, with an input current of up to 3.5A. The VI-21Y-CY-F2 DC-DC converter is a hybrid topology, which uses a combination of active components along with a transformer and other components to regulate the output voltage.

Design and Output Performance

This hybrid DC-DC converter has Active PFC with a full load efficiency of up to 97%.It also features over-voltage protection, short-circuit protection, current-limiting protection, and over-temperature protection. The output voltage is adjustable from 5V to 48V, and the output is also capable of providing up to 3.5A of output current. This makes the VI-21Y-CY-F2 suitable for powering a variety of embedded systems and LED lighting applications.

Input Voltage Range

The VI-21Y-CY-F2 can support input voltages up to 36V, making it suitable for a wide variety of applications. The converter can accept AC and DC input voltages, and the input voltage range is 4.5V to 36V. Depending on the input voltage range, the converter can operate in either constant-current or constant-voltage mode. In constant-voltage mode, the output voltage will remain constant even when the input voltage changes. In constant-current mode, the output current will remain constant even when the input voltage changes.

Working Principle

The VI-21Y-CY-F2 is a hybrid converter, which uses a combination of active components and a transformer. The active components include a power MOSFET, a switch, a rectifier, an inductor, and a PFC controller. The PFC controller is responsible for regulating the output voltage, while the transformer, inductor, and rectifier work together to store energy and regulate the output current. The input voltage is rectified by the MOSFET and switch, and the resulting DC current is then passed through the transformer to the output stage. The transformer is responsible for transferring power from the input stage to the output stage, and the output voltage is regulated by the PFC controller. When the load changes, the PFC controller will adjust the input voltage and output current accordingly, in order to maintain the output voltage at the desired level.

Conclusion

The VI-21Y-CY-F2 is a hybrid DC-DC converter that is ideal for embedded systems and LED lighting applications. It features Active PFC, over-voltage protection, current-limiting protection, and over-temperature protection. The converter can accept AC and DC input voltages, and the input voltage range is 4.5V to 36V. The converter can operate in either constant-current or constant-voltage mode, and the output voltage can be adjusted from 5V to 48V. The working principle involves a combination of active components and a transformer, in order to store energy and regulate the output voltage.
