Power Integrations InnoSwitch™3-PD ICs suit USB Type-C chargers

Power Integrations InnoSwitch™3-PD ICs simplify the development and manufacturing of USB Type-C™ and USB-PD (Power Device) power supplies. This simplification is achieved by integrating primary switch and controller, isolated feedback, secondary control, and USB-PD controller into a single compact package.
