Circuit Documentation

Summary of the Circuit

The circuit described by the provided inputs is a power supply circuit that converts AC voltage to a regulated DC output. The circuit takes an AC input from an AC source, steps down the voltage using a power transformer, rectifies the AC to DC using a bridge rectifier, and then uses a step-down buck converter to regulate the output voltage. The final output is provided through a Micro USB connector, suitable for powering or charging USB devices.
