Project Overview
The 12V 1A Switch Mode Power Supply (SMPS) is a compact, high-efficiency AC-to-DC power converter designed to provide a regulated 12V DC output at up to 1A from a universal AC input. Based on an isolated flyback topology, the power supply ensures excellent electrical isolation, stable output regulation, and reliable long-term performance. It features built-in protection mechanisms to safeguard both the power supply and connected devices, making it suitable for a wide range of consumer, industrial, and embedded applications.
