Power Integrations GaN-Based InnoSwitch3 surface-mounted package

The Quasi-resonant InnoSwitch3-CP, InnoSwitch3-EP, and InnoSwitch3-Pro ICs combine primary, secondary, and feedback circuits in a single surface-mounted package

The Quasi-resonant InnoSwitch3-CP, InnoSwitch3-EP, and InnoSwitch3-Pro ICs combine primary, secondary, and feedback circuits in a single surface-mounted package. In the newly released family members, GaN switches replace the traditional silicon high-voltage transistors on the primary side of the IC, reducing conduction losses when current is flowing, and considerably reducing switching losses during operation. This results in substantially less wasted energy and therefore increased efficiency and power delivery from the space-saving InSOP-24D package.
