MP1584 5V Regulator Circuit

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.
