Abstract: In order,a multi output switching power supply system based on UC3842 is designed for higher efficiency and stability.The reasons for choosing the chips and the requirements and principles of the main modules in power supply are analyzed.Simulation using specific software show that the switch is stable under various power outputs with an error <1% (+12 V) and an error of 2% (+5 V);the work efficiency is also significantly improved.
