Introduction to VI-2TP-IX DC DC Converters

DC-DC converters are useful devices used to convert one DC voltage level to another DC voltage level. The VI-2TP-IX DC-DC converter is a product offered by Ixys Corporation. This DC-DC converter is part of Ixys\' VI Series family of products, which includes both AC–DC and DC–DC converters. The VI-2TP-IX converter is a module designed to provide flexibility, compactness, and reliability in the regulated conversion of two isolated DC voltages.

VI-2TP-IX Application Field

The VI-2TP-IX converter provides two isolated DC output voltages. This makes it suitable for applications where two DC voltages, such as 12V and 24V, are needed. It is particularly well-suited for telecommunications applications requiring multiple isolated DC voltages. Other common applications include high-end electric power steering systems, PDAs, media entertainment systems, automotive HDDs, and LCD monitors.

VI-2TP-IX Working Principle

The VI-2TP-IX converter is a full-bridge isolated DC-DC converter. It has two input voltage sources—a primary source and a secondary source. The primary source powers the main power switches of the converter unit while the secondary source powers the control circuits. The main power switches regulate the flow of current through the transformer and thereby provide the necessary isolation between the input and output voltages. The secondary source also powers the control logic which controls the turn-on and turn-off of the main power switches. This control logic utilizes a "flyback" technique which is a self-regulating switching scheme that provides a constant output voltage regardless of input and load voltage changes.The VI-2TP-IX converter also features a built-in "control-enable" circuit. When the voltage at the "control-enable" pin is greater than 3.3V, the VI-2TP-IX converter will be in a "lock-out" mode. This means that the main power switches remain off and the converter will not be able to provide any output voltage. However, when the voltage at the "control-enable" pin is less than 3.3V, the main power switches will turn on and the converter will be capable of providing the desired output voltage.

Conclusion

The VI-2TP-IX converter is a feature-packed DC-DC converter offering two isolated DC output voltages. Its ability to provide high efficiency, flexibility, and reliability make it an ideal choice for telecommunications applications requiring multiple isolated DC voltages. The VI-2TP-IX utilizes a control-enable circuit that allows for easy control of the converter unit. The "flyback" switching scheme provides constant voltage regulation regardless of input and load voltage changes.
