Efficient Power Conversion (EPC) Announces New Family of Radiation-Hardened Enhancement-Mode Gallium Nitride (eGaN) Transistors and Integrated Circuits for Demanding Space Applications

Efficient Power Conversion (EPC) introduces a new family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions in critical spaceborne and other high reliability environments.

EL SEGUNDO, Calif.— June 2021 — EPC announces the introduction of a new family of radiation-hardened gallium nitride transistors and integrated circuits. With higher breakdown strength, faster switching speed, higher thermal conductivity and lower on-resistance, power devices based on GaN significantly outperform silicon-based devices. The lower resistance and gate charge enable faster power supply switching frequencies resulting in higher power densities, higher efficiencies, and more compact and lighter weight circuitry for critical spaceborne missions. Gallium nitride is also inherently radiation tolerant, making GaN-based devices a reliable, higher performing power transistor option for space applications.

The 48 V Revolution: Why GaN Plus Digital Control for Ultra-thin Laptops

The 48 V Revolution: Why GaN Plus Digital Control for Ultra-thin Laptops

This article discusses how GaN-based solutions coupled with digital control increase efficiency, shrink the size, and reduce system costs for high density computing applications like ultra-thin laptops and high-end gaming systems. As computers, displays, smartphones and other consumer electronics systems become thinner and more powerful over the past decade, there is increasing demand for addressing the challenge of thinner solutions while extracting more power out of limited space. To address this challenge, the comparative advantages of various non-isolated DC-DC step-down topologies for ultra-thin 48 V – 20 V power solutions that are designed to fit inside a notebook computer or an ultra-thin display are examined.
