This application note is intended to assist in designing an isolated AC-DC flyback power supply or charger using the InnoSwitch3-PD device. It provides guidelines for selecting key components and the information necessary to complete a suitable transformer design.

InnoSwitch3-PD combines a high-voltage power switch (MOSFET or PowiGaN), along both primary-side and secondary-side controllers that incorporate a USB Type-C and USB Power Delivery management,

all in one device.
