In July 2019, Power Integrations announced new members of its InnoSwitch™3 families of offline CV/CC flyback switcher ICs. The new ICs feature up to 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without requiring a heatsink.

This groundbreaking increase in performance was achieved using an internally developed high-voltage GaN switch technology -- PowiGaN™.
