This DC/DC step-down voltage converter is based on MP2303, it converts input voltage between 4.5V and 28V into a lower voltage between 0.8V and 8V, capable of driving a 3A load, with excellent line and load regulation.

Note: Input must be >1.5V higher than output! The chip may shutdown and to high temperature protection mode when operated close to its maximum power output for an extended period of time without cooling aid. It can output 3A current at 5V. This current capacity is proportionately reduced for output voltages higher than 5V.
