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.
PowiGaN-based ICs achieve up to 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without requiring a heatsink.
Design with PowiGaN-based devices
The PI Expert™ automated power supply design software suite supports both silicon MOSFET- and PowiGaN-based devices, speeding up the design process by enabling the selecting of the best components and generating the full schematic, magnetics and BOM from basic parametric inputs.
