MP1584 buck convertor

The MP1584 is a high-frequency step-down switching regulator with an adjustable output voltage, which can be set using external resistors. This example circuit demonstrates how to achieve a 5V output from an input voltage up to 24V.

Notes

Ensure all components have appropriate voltage and current ratings.
Layout is crucial for minimizing noise and ensuring stability. Place the capacitors and inductor close to the IC with minimal trace lengths.
You can use a potentiometer in place of R2 to make the output voltage adjustable within a certain range.

Applications

Battery-powered devices
Power supply for microcontrollers
Portable electronics
Any application requiring a stable 5V output from a higher voltage input

By following this guide and the datasheet recommendations, you can design a reliable 5V regulator circuit using the MP1584. Adjusting the feedback resistors allows for customization of the output voltage as per your requirements.
