PowiGaN Technology

PowiGaN is Power Integrations’ internally developed gallium nitride (GaN) technology. PowiGaN switches replace the traditional MOSFETs 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.

Pioneering High-Voltage GaN Power Devices for a Wide Range of Applications
