When the issue invariably turns to the packaging of the power semiconductor – transistor, diode, or integrated circuit – the requests for improvement fall into six categories:

1. Can you make the package smaller?
2. Can you reduce the package inductance?
3. Can you make the product with lower conduction losses?
4. Can you make the package more thermally efficient?
5. Can you sell the product at a lower price?
6. Can you make the package more reliable?

New converter topologies and power transistors promise to reduce the size and boost the efficiency of supplies that will run next-generation Artificial Intelligence (AI) platforms. In all the topologies with 48 V_IN, the highest efficiency comes with using GaN devices. This is due to their lower capacitance and smaller size. With recent pricing declines in GaN power transistors, the cost comparison with silicon-based converters now strongly favors GaN in all the leading-edge solutions.

In the final installment of this series, how GaN has met the requirements to displace silicon is explored. As the adoption rate of GaN explodes, it is important to remember that, while GaN has made many advancements in just a few short years, it is still far from its theoretical performance limitations and thus there are profound improvements that can continue to be achieved. In time, the performance and cost advantages of GaN-on-silicon will result in a majority of applications currently using silicon-based devices converting to the smaller, faster, cheaper, and more reliable GaN technology.
