Power Integrations Unveils Revolutionary 1700 V GaN Switcher IC
SAN JOSE, Calif. — Power Integrations, Inc. (NASDAQ: POWI), a world leader in high-voltage integrated circuits for energy-efficient power conversion, is excited to announce the introduction of its groundbreaking 1700 V GaN InnoMux-2 IC. This innovative device sets a new benchmark for gallium nitride (GaN) technology in the power conversion industry.
Efficiency and Power Supply
The 1700 V GaN InnoMux-2 IC is engineered for efficiency, boasting better than 90 percent efficiency when powered from a 1000 VDC bus. It can supply up to 70 watts from three accurately regulated outputs, a significant upgrade from its predecessors.
Technological Advancements
This latest GaN IC employs the first-ever 1700 V gallium nitride switch, crafted using Power Integrations' proprietary PowiGaN™ technology. This advanced fabrication technique represents a remarkable feat in the field of power electronics, as it further enhances the state-of-the-art performance for GaN power devices, following the successful launches of their 900 V and 1250 V devices over the last two years.
Unprecedented Applications
Designed to replace costly silicon carbide (SiC) transistors, the 1700 V InnoMux-2 is ideal for a variety of applications including automotive chargers, solar inverters, and various industrial power systems. Its impressive specifications allow it to handle 1000 VDC nominal input voltage and easily achieve over 90 percent efficiency.
Highly Accurate Voltage Regulation
Each output of the InnoMux-2 IC is regulated within 1 percent accuracy. This remarkable precision eliminates the need for post regulators, leading to further system efficiency improvements of approximately ten percent.
Insights from Industry Experts
Radu Barsan, Vice President of Technology at Power Integrations, remarked on the rapid advancements in GaN technology, stating, "In less than two years, we've achieved three world-first voltage ratings with our GaN products: 900 V, 1250 V, and now 1700 V. The InnoMux-2 IC integrates independent, accurate regulation with our FluxLink™ secondary-side communication technology and introduces zero-voltage switching (ZVS) without the traditional active clamp, effectively minimizing switching losses.
The Future of Power Electronics
Ezgi Dogmus from Yole Group shared that the current market for power GaN devices is projected to reach approximately $2 billion by the end of the decade, emphasizing the growing demand for GaN technologies across diverse applications.
Availability and Pricing
The InnoMux-2 1700 V ICs are competitively priced starting at $4.90 for bulk orders of 10,000 units. For designers interested in exploring the capabilities of this IC, a reference design (RDR-1053) describing a 60 W dual-output power supply is available for download at no cost on the Power Integrations website.
