Overview

Description

MP2249DN-LF-Z is a dual synchronous buck regulator IC from Monolithic Power Systems. It integrates two high-efficiency N-channel MOSFETs and the control circuitry needed to generate two low-voltage rails from a higher input supply. The device uses current-mode PWM with soft-start, includes an enable/shutdown input, and provides protection features such as overload/current limit, over-temperature, and UVLO. It can be used for either two independent outputs or a dual‑phase interleaved VRM, delivering high efficiency via synchronous rectification. The LF suffix indicates a lead-free package, with -Z options for tape-and-reel. Typical applications include CPU/GPU core power, motherboard VRMs, and other compact embedded/telecom power supplies. For exact electrical specs, pinout, and recommended circuits, consult the MP2249DN-LF-Z datasheet.

Package

The MP2249DN-LF-Z is packaged in a lead-free 16-pin QFN (DN) package, 3.0 mm × 3.0 mm, supplied on tape-and-reel (Z).

Manufacturer

Manufacturer: Monolithic Power Systems (MPS).
What kind of company: MPS is a fabless semiconductor company that designs and supplies power-management integrated circuits (switching regulators, PMICs, LED drivers, battery-management ICs and related analog/mixed-signal products) for consumer, industrial, automotive and telecom applications.
