MP1584EN-LF 3A buck switching regulator IC 0.8V 1 Output 3A
The MP1584EN-LF is a high-frequency, high-efficiency 3A buck switching regulator from Monolithic Power Systems (MPS) that integrates an internal high-side high-voltage power MOSFET to deliver compact and efficient power conversion. Operating from a wide 4.5V to 28V input range with adjustable output from 0.8V to 20V, this device achieves up to 96% conversion efficiency at 1.5MHz switching frequency, enabling the use of small passive components and reduced PCB footprint. Housed in a thermally enhanced 8-pin SOIC package with exposed pad, it features current-mode control for fast transient response and includes comprehensive protection features including overcurrent protection, thermal shutdown, and under-voltage lockout, making it ideal for space-constrained embedded and industrial power applications.
