The MP1584 Mini DC-DC Switch Mode Buck Converter is a step-down voltage converter based on the widely popular MP1584 chip. It is capable of converting a high input voltage of between 4.5V and 28V, down to a lower voltage of between 0.8V and 25V DC, with an output current of between 2A minimum and 4A peak. This is ideal for projects in which you need to supply a constant, regulated current, and this module allows you to use a wide range of different Power Supplies without having to worry about specific voltage and current ratings or limits.

This Electronics Module, despite being small with a relatively low population of components, features an impressive efficiency rating of around 95%, with a programmable switching frequency for controlling precise PWM duty cycles. It also offers high-efficiency Pulse Skipping Mode for light loads, which eliminates the chances of providing too much power to Components, while also ensuring that they get the precise amount of power to operate at optimal efficiency. And finally, this module is designed to ensure the lowest amount of ripple possible, with an output ripple of less than 30mV. This keeps the output voltage very stable, which is critical if you are using this module for low power or light load Electronics.
