What is PowiGaN?
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.
