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.

Which PI Products Feature PowiGaN Technology?
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.
- InnoSwitch3-CP - best for constant power charging
- InnoSwitch3-EP - best for open frame power supplies
- InnoSwitch3-Pro - best for dynamically controllable voltage and current, including USB PD PPS applications
- InnoSwitch3-MX - best for LED TVs, monitors and appliances utilizing LED displays, paired with InnoMux controller
- MinE-CAP - best for reducing capacitor size in chargers, paired with InnoSwitch3 switcher ICs
- LYTSwitch-6 - best for LED lighting and ballast
