VE-21L-CV-F4

DC-DC Converters

DC-DC converters are electrical circuits which convert DC input (or AC input) to a different DC voltage. Generally, the input can typically be a battery or a solar panel, while the output is usually some form of regulated DC voltage. They are commonly used in many applications including industrial, automotive, aerospace, and consumer markets. From the simplest buck step-down converter to the most sophisticated high-efficiency switching regulators, DC-DC converters can be found in a wide variety of applications.

VE-21L-CV-F4 Application Field and Working Principle

The VE-21L-CV-F4 is a wide input, high efficiency, dual output DC-DC converter designed for lighting and high power applications, such as industrial, automotive, and aerospace. It features wide input voltage range from 9 - 60V DC, an adjustable output voltage and a 36V maximum load current. The VE-21L-CV-F4 can be used to convert an unregulated DC input into a regulated DC output, providing a reliable, stable and configurable power supply.

The working principle of the VE-21L-CV-F4 can be summed up as follows: The input voltage is first regulated by a PWM controller and is then an amplified and rectified voltage is used to drive a synchronous rectifier. A special control scheme keeps the inductor current within its pre-set limits, while the voltage loop maintains the load regulation and the temperature loop keeps the converter within its thermal limits. Finally, the output voltage is fully adjusted by a trim potentiometer, allowing the user to easily adjust the output voltage as necessary.

The VE-21L-CV-F4\'s wide input voltage range, adjustable output voltage, and fast load transient response make it a suitable choice for many applications. It features a high efficiency of up to 96% and a low output ripple voltage of less than 2%. Its main advantages compared to other DC-DC converters are its reliability, efficiency, and the ability to operate from a wide range of input voltages. Additionally, the VE-21L-CV-F4 has a very low standby power consumption in comparison to other DC-DC converters on the market.
