PowiGaN Technology
PowiGaN is Power Integrations’ internally developed gallium nitride (GaN) technology. PowiGaN switches replace the traditional silicon transistors on the primary side of PI’s highly integrated offline flyback switcher ICs, reducing switching losses and enabling chargers, adapters and open frame power supplies that are more efficient, smaller and lighter than silicon alternatives.
Power Integrations continues to lead the advancement of GaN technology, expanding the switching voltage and elevating GaN as a mature, dependable semiconductor technology for even the most demanding applications.
The Industry's first 1700 V GaN Switch
In less than two years, Power Integrations has delivered three voltage-rating breakthroughs from 750 V to 900 V, and now 1700 V. The 1700 V voltage rating marks a watershed moment in the advancement of GaN power electronics, making it possible for GaN devices to replace costly silicon carbide (SiC) transistors in high-voltage applications.
Pioneering High-Voltage GaN Power Devices for a Wide Range of Applications
InnoSwitch3-EP for Appliances and Industrial Use

Standard-Setting Quality and Reliability
GaN devices for power conversion first became commercially available in volume in the fall of 2018, when Power Integrations began shipping PowiGaN-based products. Since then, the PowiGaN switch has accumulated over a trillion hours of operation with extremely low failure rates.
As the industry begins to establish standardized reliability assessments for GaN devices, Power Integrations remains steadfast in our mission: to not only meet industry standards but to lead the way in defining reliability for this exciting new technology.
Reliability has been at the forefront of our GaN development, as all PowiGaN products go through rigorous testing, surpassing both traditional and GaN-specific benchmarks. PI Vice President of Marketing and Applications Engineering Doug Bailey breaks down the quality, robustness and reliability of PowiGaN in this video.
