It can be used in a variety of automotive power systems, such as microinverters, active motor drive, and safety-critical systems. In addition, it can be used as an on-board power supply to support power management systems while saving energy and protecting electronic components.

Working Principle of VE-21K-CV-F1

The VE-21K-CV-F1 utilizes a unique and highly-efficient architecture that allows the converter to provide a wide input voltage range, while reducing current consumption during operation. The converter operates on a step-down current-mode topology, which means that the input voltage is stepped down to generate the output.

The converter consists of an input regulator, a DC/DC converter, an output regulator, and a feedback loop circuit. The input voltage begins at a provided voltage range, and is then regulated by the input regulator to step down the voltage. The stepped-down voltage then passes through the DC/DC converter to further reduce the voltage and increase the current. This is done by regulating the output voltage using an output regulator.

The output regulation is then monitored in the feedback loop circuit. If the output voltage is higher than the provided target voltage, the feedback loop circuit will reduce the output, which in turn will reduce the current output. If the output voltage is lower than the target voltage, the feedback loop circuit will increase the output, which will increase the output current.

Once the output voltage reaches the target voltage, a steady-state is reached and the output current remains constant. The current at the output of the converter is then used to meet the power requirements of the device being supplied.

Conclusion

The VE-21K-CV-F1 is a DC DC converter that can be used in a variety of automotive power systems. It utilizes a unique and highly efficient architecture that allows the converter to provide a wide input voltage range, while reducing current consumption during operation. It is an ideal solution for applications that demand low noise, light weight, and small size.
