應用說明

This design guide provides engineers with instructions on how to design an isolated DC-DC flyback power supply for automotive applications using the InnoSwitch3-AQ family of ICs. These devices can accurately regulate output voltage even with a wide input voltage range of 30 VDC to >1000 VDC, making them suitable for functional safety critical emergency power supplies.

This document provides guidelines for using hardware and software filters to mitigate high noise levels in applications with electrically noisy environments when using SCALE EV products with Bitstream technology to ensure accurate readings from the bitstream signal.

This application note is intended for engineers designing an isolated AC-DC flyback power supply or charger using the InnoSwitch3 family of devices. It provides guidelines to enable an engineer to quickly select key components and also complete a suitable transformer design.
