DC-DC converters are devices that convert direct current (DC) from one voltage level to another. The VE-B2T-MY-S is a form of DC-DC converter developed by Vicor Corporation specifically for applications where space and cost savings are of paramount importance. This article seeks to provide an overview of the VE-B2T-MY-S application field and working principles, as well as explain why it is such an attractive option for applications where size and cost are key considerations.

The VE-B2T-MY-S is a single-stage DC-DC converter designed to provide regulated outputs from unregulated inputs in a wide range of industrial and commercial applications. It is optimised for working with low-voltage DC input sources, such as 24V batteries, solar panels, and automotive alternator fields, and can provide a wide range of output voltage regulation for applications including, but not limited to, industrial control, communication systems, home security systems, automotive electronics and renewable energy products.

The main advantage of the VE-B2T-MY-S is its compact size. The converter has a total package width of just 6.5 mm, allowing it to fit into tight spaces, and can be mounted to existing heat sinks without a significant increase in size or cost. This makes it ideal for applications where space, cost and weight are considered a premium.

In terms of operating principle, the VE-B2T-MY-S is a buck-boost converter. This type of converter is able to maintain a high input-output voltage ratio, while also providing regulated output voltage timing. The workings of the VE-B2T-MY-S can be broken down into two separate stages: an input stage and an output stage. The input stage consists of an input rectifier, which converts the input AC voltage to a pulsing DC voltage. This pulsing DC voltage is then converted to a regulated pulsing DC voltage using a buck-boost converter. The output stage then converts the pulsing DC voltage back to a regulated DC voltage.

The VE-B2T-MY-S also provides several protection features, including output over-voltage protection, short-circuit protection and thermal shutdown protection. The converter also features a low start-up current of 15mA, allowing it to operate continually with minimal drain on the input source. This helps to increase the overall efficiency of the converter and save on operating costs. Additionally, the VE-B2T-MY-S can also be specified with a wide range of feedback options, allowing it to be tailored to the needs of specific applications.

In conclusion, the VE-B2T-MY-S is a compact, cost-effective DC-DC converter that is suitable for a wide range of low-voltage applications. Its buck-boost design provides reliable voltage regulation and protection features, while its low start-up current ensures an efficient and cost-effective operation. The VE-B2T-MY-S can also be customised to meet the needs of specific applications, making it an attractive and versatile choice for applications where size and cost are key considerations.
