MP1584 DC-DC Step Down Regulator IC 3A SOIC-8E

The MP1584 is a high-efficiency DC-DC step-down (buck) switching regulator IC designed for compact and reliable power conversion. With a wide input voltage range of 4.5V to 28V and adjustable output from 0.8V to 25V, it delivers up to 3A continuous output current, making it suitable for a wide variety of power management applications.

Featuring current-mode control, fast transient response, and programmable switching frequency up to 1.5MHz, the MP1584 ensures stable and efficient operation across different load conditions. Built-in thermal shutdown, internal soft-start, and frequency foldback protection enhance reliability and fault tolerance. Its high switching frequency reduces EMI and allows smaller external components, ideal for space-constrained designs. Housed in a thermally enhanced SOIC-8E package.
