DC-DC converter is a kind of parameter regulator with DC output voltage, which is used to convert the power source voltage value of different levels to the voltage value of the expected level. In particular, the VI-26Y-IY-S converter can not only be used for frequency conversion applications such as power supply, but also can be used to isolate the input and output side and prevent the user from potentially dangerous signals. This kind of DC-DC converters can be classified into four categories: voltage mode, current mode, pulse width modulation (PWM) and resonant converters. The VI-26Y-IY-S converter belongs to the voltage mode DC-DC converter, and its application fields and working principle are introduced here.

The application range of VI-26Y-IY-S converter is mainly in the fields of communication system, high precision instrument system, automotive accessories and so on. It has wide external adjustment range that can meet the application requirement of different users. In addition, its wide operating temperature range and high isolation voltage are also favored by users.

The working principle of VI-26Y-IY-S converter is mainly based on the principle of voltage regulation. It is a kind of linear voltage regulator converter. According to the adjustable output voltage, a precision reference voltage is generated at the reference terminal of the control chip, and the difference between the output voltage and the feedback voltage is sent to the error amplifier as an error signal. The error amplifier amplifies the signal to obtain the control signal of the switching transistor, and the switching transistor is driven to operate accordingly to achieve the purpose of voltage regulation. The switching transistor works alternately in different conduction states to realize the purpose of voltage conversion.

In addition, the VI-26Y-IY-S converter has built-in temperature compensation module, which can automatically correct the output voltage value according to the ambient temperature changes, so as to maintain the stability of output voltage. It also has over voltage waring and protection function, which can prevent the electronic device from being damaged in case of excessive voltage input. The power conversion efficiency of the converter can be as high as 95%, which can effectively save energy.

In conclusion, VI-26Y-IY-S converter is a kind of widely used voltage mode DC-DC converter, which has wide application fields and high efficiency. It is equipped with temperature compensation, overvoltage protection and other functions, which can ensure the stable output voltage and improve the safety performance of the system.
