VXR250-2828S DC-DC Converter

The VXR Series of isolated DC-DC converters is the latest and most advanced offering in VPT’s extensive line of high reliability COTS products. Building on a proven design heritage, the VXR Series features high efficiency, an ultra-wide input voltage range, and next-generation packaging. Providing a wide 11 V to 60 V input, along with VPT’s standard full feature set and industry-leading performance, the VXR family is optimized for a broad range of applications from military ground vehicles to commercial and military aircraft. The VXR250 utilizes a low noise, fixed frequency, wide input voltage range topology with extended high and low input transient capability to simplify overall power system design and compliance. Precision controlled synchronous rectification achieves high efficiency over a wide input range, reducing power dissipation and minimizing external heatsink requirements. A proprietary control loop design provides fast transient response without the use of optoisolators.
