The Power Integrations InnoSwitch3-PD dramatically simplifies the development and manufacturing of USB-PD power supplies by integrating primary switch and controller, isolated feedback, secondary control and USB-PD controller into a single package. It's secondary controller consists of a transmitter circuit that is magnetically coupled to the primary receiver, an I2C interface to control power supply parameters and telemetry functions, a 4.4 V regulator, SR FET driver, QR mode circuit, oscillator and timing functions, and a host of integrated protection features.
