MP2305DS-LF

MP2305DS-LF Description

The MP2305DS-LF from Monolithic Power Systems (MPS) is a high-efficiency, synchronous buck regulator designed for DC-DC voltage conversion in a wide range of applications. This adjustable output regulator delivers up to 2A of continuous output current with an input voltage range of 4.75V to 23V, making it suitable for both low and medium-power systems. The output voltage can be adjusted from 0.923V to 20V, providing flexibility for various load requirements. Operating at a switching frequency of 340kHz, it balances efficiency and component size, while its synchronous rectification enhances power conversion efficiency. Packaged in an 8-pin SOIC and compliant with ROHS3 and REACH, it is ideal for surface-mount PCB designs.
