Overview

The MP2315GJ-Z is a high-frequency, synchronous, rectified, step-down switch-mode converter with built-in internal power MOSFETs. It offers a very compact solution that achieves 3A continuous output current over a wide input supply range of 4.5V to 24V, featuring excellent load and line regulation.

Why Choose This Part

The device utilizes synchronous rectification for high efficiency and features internal compensation to minimize external component count. Its TSOT-23-8 package provides a small form factor while handling up to 3A, and the wide 24V input range accommodates various standard industrial and consumer power rails.

Applications

Distributed Power Systems
Ideal for point-of-load regulation in industrial and networking equipment requiring high efficiency and small footprint.
Digital Set-Top Boxes
Provides stable low-voltage rails for processors and memory from 12V or 19V adapter inputs.
Flat Panel Television Power
Used to step down main bus voltages to power internal logic and peripheral circuits.
Computing Peripheral Supplies
Efficiently converts standard 12V supply rails into 3.3V, 1.8V, or 1.2V rails for high-performance peripherals.
