VPT, Inc. unveiled its latest point of load (POL) DC-DC converter today, the DVPL0503S. This new converter joins VPT’s growing line of POL DC-DC converters that deliver critical reliability performance and efficiency in the distributed power architectures of avionics, military, and space systems.

The new 3A DVPL DC-DC POL converter can be used alone or in conjunction with the DVHE 50W DC-DC converter as part of VPT’s High Efficiency, Reliability Optimized (HERO) Power System. The DVPL 3A POL converter is a non-isolated, synchronous, buck regulated converter that steps down the voltage at the point of end use. Its tiny size and light weight save board space, weight, and expense, making it an improved solution over the use of multiple isolated DC-DC converters to power individual loads in an electronics system.

“Today’s commercial avionics, military and space electronics demand higher performance while decreasing size, weight and cost. The power supply is a key factor in a system’s size, weight, and thermal design. That’s why we recommend our HERO distributed architecture, which consists of a single isolated DC-DC converter used in conjunction with smaller, lighter, more efficient point of load converters including our new 3A POL,” explained Michael J. Bosmann, Senior Vice President of Marketing and Sales. “This new POL joins our family of POLs for a breadth of flexible design options, resulting in a smart, small, efficient power system.”

The DVPL0503S is designed and built to military-grade reliability as defined in MIL-PRF-38534. With the addition of the new 3A DVPL POL converter to VPT’s current offerings of 5A and 10A POL converters, engineers now have a wide variety of POL converters to choose from, ensuring complete flexibility in designing a power system.
