Project Overview
The 5V 2A Switch Mode Power Supply (SMPS) is a compact, high-efficiency AC-to-DC power converter designed to deliver a regulated 5V DC output at up to 2A from a universal AC input. Based on an isolated flyback topology, the power supply provides excellent electrical isolation, stable output regulation, and reliable performance. It incorporates comprehensive protection features, making it suitable for USB-powered devices, embedded systems, networking equipment, and various consumer and industrial electronics.
