The demand for efficient power management in space continues to grow due to the increasing complexity and frequency of space missions, particularly with the expansion of small satellite deployments and interplanetary exploration. The advancement of satellites and spacecraft requires reliable power systems for energy distribution, storage, and conversion. Efficient power management optimizes space system operations, extends mission duration, and reduces operational costs. DC-DC converters are essential components in managing power from renewable sources like space-based solar systems, ensuring stable operation of spacecraft and satellite subsystems in extreme conditions.
 

The trend toward satellite miniaturization and the integration of complex systems into smaller spacecraft, particularly in small sats and CubeSats, demands compact and lightweight components, including DC-DC converters. These components must maintain high performance despite size and weight limitations. The demand for space DC-DC converters is rising as satellites require power management across multiple subsystems, including communication modules, sensors, and propulsion systems.
 

For instance, in May 2024, Microchip Technology released its LE50-28 series of Radiation-Tolerant (RT) isolated DC-DC 50W power converters for Low-Earth Orbit (LEO) applications. Power converters serve various applications including 5G communication, cube satellites, and IoT systems. The series offers nine variants with single- and triple-output configurations from 3.3V to 28V, supporting satellite miniaturization and efficient power systems in small satellites.
