GaN Systems has introduced its ground-breaking fourth-generation GaN power platform. This state-of-the-art technology establishes a new power efficiency and compactness standard, providing an impressive step-function performance boost and industry-leading figures of merit. For example, with GaN Systems Gen4 in an AI server rack, 3.2kW power supplies at 100W/in3 in 2022 are now attaining 120W/in3 with efficiencies above Titanium levels. Gen4 will revolutionise power markets, including consumer electronics, data centres, solar energy, industrial applications, and automotive.
The Gen4 platform also supplies more total BOM cost savings than traditional Silicon and Silicon Carbide solutions, making the company's technology a powerful option for businesses striving to enhance their competitive advantage.
"Our lead customers have already realised the benefits of our Gen4 platform," stated Jim Witham, CEO of GaN Systems. "This platform is a testament to our ongoing commitment to continuously delivering superior performance advantages and next-generation levels of efficiency. GaN Systems, in strategic collaboration with industry leaders like TSMC, has invested significantly to meet the ever-evolving demands of our customers. We are pioneering a transformation in product offerings, packaging innovations, enriched functionalities, and unparalleled performance across our markets."
The power platform delivers >20% improvement in input and output figures-of-merit, which reduces losses, enhances efficiency, and more cost-effective solutions. It provides increased granularity in device specification, combined with a wide range of packaging options, including PDFN, TOLL, TOLT, and Embedded – allowing the correct Rds resistance and package combination for each application, consequently optimising electrical and thermal system performance. Supplying 700V E-mode with the industry's highest transient voltage rating, 850V significantly enhances total system reliability and robustness. This rating allows the semiconductor components to withstand user environment anomalies, such as voltage spikes, ensuring uninterrupted and dependable performance. The on-state resistance ranges allow power systems from 20W to 25,000W.
