DC-DC Power Conversion

GaN Increases Efficiency, Reduces Size and Weight, and Improves Reliability

GaN technology allows power supply designers to optimize their designs for size and weight, efficiency, EMI, and power density. The increased switching capability and reduced parasitics equate to lower losses enabling engineers to increase the switching frequency resulting in reduced size and weight of magnetic components, a reduction or elimination of heat sinking, and lower copper losses. These benefits result in an overall reduction of system size and weight without a sacrifice to efficiency. GaN-based power supplies operate at higher frequencies, higher efficiencies, and greater power densities for Micro, low-Earth orbit (LEO), geosynchronous- Earth orbit (GEO) satellites, along with deep space and outer space explorations, smaller and lighter onboard power supplies in robotics, and other high reliability aerospace and defense systems.

Devices range from 15 V – 350 V to cover a wide range of bus voltages and derating requirements
