Description
The circuit produces an output of 5V and 1A, it is mainly used in cell phone chargers, microcontrollers, Bluetooth/WiFi modules etc. The circuit board converts an input voltage of 220V AC and converts it into a 5V DC output. The circuit has a transformer that steps down the voltage from 220V AC to 5V AC, The four diodes in the circuit act as a rectifier that converts the AC voltage to DC voltage. The circuit consists of numerous resistors and capacitors, which acts as filters. The resistors and capacitors smooth the current and the voltage flow giving an approximate, average voltage value that is required.

Further Info
The 5V 1A Switch Mode Power Supply Module (SMPS) can be used to power low-power electronic circuits such as battery chargers and LED drivers. This is a low-cost power supply module based on transistors that can be utilised in low-power projects.
This module is simple to use: simply connect the input AC lines to the proper pins on your wall socket and get a regulated power supply as output from the module's output pins. You don't need to attach any additional circuitry because it has built-in stabilising capacitors and protection circuits. Read more
