DC DC converters are used to regulate the output power of a DC motor. The VI-25Y-IY-F1 is one such converter. It is designed to provide a regulated output voltage with maximum efficiency with minimum standby power consumption.

Specifications

The VI-25Y-IY-F1 is a synchronous DC DC converter with an input voltage range of 4.5V to 36V and a power range of 25A with a voltage output of 12V-24V. It has a peak efficiency of 93%, efficiencies of up to 90% over the entire output power range, and can provide a high frequency operation (up to 300kHz). It also features soft start, adjustable output voltage, adjustable current limit, over temperature protection, input overvoltage protection, reverse polarity protection and external synchronization.

Application Field

This DC-DC converter is mainly used for power supply of microprocessor-based systems, computers, consumer electronic devices, etc. It can also be used in applications such as linear regulators, charge pumps, voltage regulators, and power conditioning. The wide input voltage range and adjustable output voltage make it suitable for use in a variety of applications. It is also capable of providing constant voltage or current while being able to operate in different environmental conditions.

Working Principle

The VI-25Y-IY-F1 is a step-down DC-DC converter. It works by using a synchronous rectifier and PWM technique to switch the incoming voltage into the desired output and then regulating it using a pulse width modulated signal. The converter receives an input voltage, which is then switched into the proper output voltage using the synchronous rectifier and PWM. This allows for high efficiency operation and better voltage regulation. Additionally, a feedback loop ensures that the output voltage remains stable.

The converter is protected from overvoltage and reverse polarity by protection circuits. The input overvoltage protection circuit is located at the input pins and will turn off the converter when the input voltage exceeds the maximum rated value. The reverse polarity protection circuit will turn off the converter when the reverse voltage is applied to the input. These protection circuits help to prolong the life of the converter and other connected devices.

The VI-25Y-IY-F1 DC DC converter can provide a stable output power with a high efficiency and adjustable output voltage. The wide input voltage range and adjustable output voltage make it suitable for use in a variety of applications. Its robust protection circuits protect it from overvoltages and reverse polarities. Additionally, its small size and light weight make it ideal for use in a variety of applications.
