This design is a power supply system that converts 240V AC (60Hz) into three regulated DC outputs. The architecture includes an AC rectifier and filter to form a DC bus, followed by a boost converter (MT3608) that steps up the voltage to 5V. From the boosted output, three voltage regulators provide different outputs: a 5V rail directly from the boost converter, a 3.3V rail using the AP7333-33 buck converter, and a 1.8V rail using the AP7333-18 buck converter. Protection components such as Schottky diodes and stability capacitors are incorporated, along with LED indicators for charging and power status. #PowerSupply #VoltageRegulation #ACDCConversion #BoostConverter #BuckConverter #CircuitDesign #PowerSystemArchitecture
