What is this project about?

The Mini 560 is one of the most popular compact DC-DC Buck converter 

modules in the maker community. It delivers a fixed 5V output with 

up to 3A peak current in an ultra-small 17x11mm footprint, making it 

perfect for powering microcontrollers, sensors, and IoT devices.

Why did I make it?

I needed a reliable, low-cost 5V power module for my IoT and embedded 

projects. I reverse-engineered the original Mini 560 module and 

optimized the Gerber files for PCBWay standard 2-layer process.

How does it work?

The JW6058A is a high-efficiency synchronous Buck controller switching 

at ~500 kHz, regulating the output to a fixed 5V from a wide input 

range (4.5V to 23V). Clean output with ripple below 30mV, suitable 

for sensitive microcontroller applications.
