_{This article is classified as DC DC Converters}
DC-DC converters are electronic devices that convert direct current (DC) from one voltage level to another. The DVE0125V2N1C is a type of DC-DC converter specifically designed for both isolated and non-isolated applications. It features very low power dissipation and offers high efficiency. This device combines high power density with an enabling circuitry which provides for easy integration of the converter in the system without the need for any external components.

Application Field

The DVE0125V2N1C is designed for a wide range of applications such as mobile phones, notebook PCs, servers, HDDs, gaming systems, automotive electronics, and communication. The operating temperature range of this device is -40°C to +105°C, withstanding up to 90% relative humidity. This provides great flexibility for applications in various environments.The device also provides protection features such as over-voltage protection and current limit protection, making it suitable for applications with limited space or power redundancy requirements. It offers excellent load and line regulation, as well as low noise during operation.

Working Principle

The DVE0125V2N1C uses step-down topology, employing a buck converter as the power conversion stage. This device uses a pulse width modulation (PWM) controller to regulate the voltage and current output. The pulse width modulation control signal is generated from a signal generator block, where an oscillator generates a constant frequency signal and an error amplifier is used to compare the output voltage to the reference voltage.The output voltage of the buck converter is then regulated by controlling the duty cycle of the PWM controller. This is achieved using a voltage feedback, where the output voltage is compared with the reference voltage and the difference is used to adjust the duty cycle of the PWM.In addition, current-limit protection is also provided in the device. This is especially useful when a fault occurs during system operation. The current-limit circuitry monitors the current through the device, and shuts down the entire system when the current exceeds the predefined threshold.

Summary

The DVE0125V2N1C is a versatile DC-DC converter designed to offer high efficiency and low power dissipation. It is designed for applications such as mobile phones, notebooks, servers, HDDs, gaming systems, automotive electronics, and communication. This device employs step-down topology with a buck converter as the power conversion stage, and uses a pulse width modulation controller for voltage and current stability. The device also features over-voltage protection and current-limit protection for system safety and reliability.
