DC DC Converters

DC-DC converters, also known as DC-DC switching regulators, are electronic devices that can transform and regulate an input direct current (DC) voltage to a desired output voltage. This transformation and regulation is required in a wide range of applications, which can also vary greatly depending on the particular power supply design and operating needs.

VI-2WX-IW-B1 Application Field and Working Principle

The VI-2WX-IW-B1 DC-DC converter is a twist-lock type converter developed for use in industrial as well as some household applications. The device features a step-up regulation, allowing it to convert low voltage inputs into higher output voltages in a variety of ranges. Its output is adjustable, drifts slowly in response to temperature, and is protected from overloads and short-circuits.

The VI-2WX-IW-B1 converter utilizing a full-bridge converter topology, where four switches are connected in series and two of the switches are in reverse polarity. This type of topology reduces input current ripple while providing steady operation, and the converter is able to achieve a load regulation of 20 mV, with a voltage accuracy of 0.75% at full load.

The frequency of the VI-2WX-IW-B1 DC-DC converter is also adjustable, allowing for better control over the current output and greater efficiency in power conversion. The device can operate at both medium and high frequencies, ranging from 6 kHz to 1.5 MHz. Additionally, it has built-in soft-start functionality, which helps to reduce the input current during initial start-up.

VI-2WX-IW-B1 DC-DC converters are mainly used in industrial applications, such as industrial motor drives, machine control, networking, and battery charger systems. The device is also suitable for use in high-reliability projects, thanks to its low noise operation and high efficiency of up to 90%. Its unique design also makes it suitable for over-voltage and over-temperature protections, making it an ideal choice for challenging applications that require a rugged design.

Overall, the VI-2WX-IW-B1 DC-DC converter is ideal for a variety of power supply designs and operating needs, due to its adjustable input and output, high efficiency, and wide operating range. Its rugged design and advanced features also make it a good choice for industrial applications where reliability and performance are paramount.
