Electrifying Everything: Power Moves Toward ICs
By Gregory Haley - 23 Jan, 2025 - Comments: 0

As electronic systems grow increasingly complex and energy-intensive, traditional power management methods — centered on centralized systems and external components — are proving inadequate. The next wave of innovation is to bring power control closer to the action — directly on the chip or into a heterogeneous package. This change is driven by a relentless pursuit of efficiency, scala... » read more

Improving GaN Device Architectures
By Katherine Derbyshire - 23 Jan, 2025 - Comments: 0

As the universe of applications for power devices grows, designers are finding that no single semiconductor can cover the full range of voltage and current requirements. Instead, combination circuits use different materials for different parts of the overall operating range. GaN is especially well-established in low-power applications like chargers for personal electronics, while silicon and... » read more

Challenges In Powering Electrification With GaN And SiC
By Katherine Derbyshire - 17 Dec, 2024 - Comments: 0

The wish list of device properties that designers of power management systems would like to have is lengthy, but no single material is yet sufficient for the full range of power control applications. For control transistors to handle power surges, breakdown voltages should be at least triple the expected operating voltage — 1.2 kilovolts or more for many electric vehicle applications, and ... » read more
