This is a compact DC-DC step-down (buck) converter module designed to efficiently convert an input voltage of 7-12VDC into a stable 5V output, capable of supplying up to 3A.
The ET-MINI PWR5 module is a reliable switching regulator board built around the LM2576T-5.0 IC, a high-efficiency step-down voltage regulator. It accepts a DC input voltage ranging from 7V to 12V and provides a fixed, regulated 5V output, making it ideal for powering various 5V electronic circuits and microcontrollers.
