MPQ4316GRE-AEC1-Z 产品概述

一、产品简介

MPQ4316GRE-AEC1-Z 是 MPS 提供的一款高性能降压型 DC-DC 转换器,具有宽输入电压范围、高效率和丰富的保护与控制功能。器件集成高侧/低侧开关(同步整流),开关频率 1MHz,适合空间受限且对效率、EMI 有较高要求的电源设计,封装为 QFN-20(4×4),符合汽车级工作温度要求(-40℃ ~ +150℃)。

二、主要参数

  • 功能类型:降压型(同步整流)
  • 输入电压:3.3V ~ 45V
  • 输出电压:可调 0.815V ~ 42.75V
  • 最大输出电流:6A
  • 开关频率:1MHz
  • 静态电流(Iq):18µA(轻载高效模式下)
  • 开关管:内部集成
  • 输出通道数:1
  • 工作温度:-40℃ ~ +150℃
  • 封装:QFN-20(4×4)
  • 型号/品牌:MPQ4316GRE-AEC1-Z / MPS

三、核心功能特性

  • 轻载高效模式:在低负载条件下自动进入低损耗工作态,显著降低静态功耗,适用于待机或间歇供电场景。
  • 频率同步:支持外部时钟同步,便于与系统中其他开关电源协同工作,减少干扰耦合。
  • 可调软启动:通过外部电容设置软启动时间,有利于系统上电冲击管理并避免输出过冲。
  • EMI 优化(抖频/扩频):内建抖频功能可扩展频谱,降低窄带 EMI 峰值,便于满足电磁兼容要求。
  • 工作状态指示:提供状态引脚用于输出使能/故障指示,便于系统监控。
  • 打嗝限流:短路或过流条件下进入打嗝限流模式,限制热应力并支持自动恢复。

四、典型应用

适用于点对点电源、工业控制、通信设备、车载电子(型号含 AEC 指示汽车级)、分布式电源模块、便携终端与多路隔离电源前级等需要宽输入、6A 级输出且对效率与 EMI 管控敏感的场合。

五、设计与布局建议

  • 输入/输出电容:采用低 ESR 陶瓷电容靠近芯片 VIN 与 VOUT 引脚,以抑制开关噪声与环路振荡。
  • 电感选择:围绕 1MHz 频率和 6A 输出设计合适电感值,注意饱和电流高于峰值电流。
  • 散热措施:QFN 热焊盘需接大面积铜箔并通过多层过孔回流至散热层,保证在高温与大电流下的稳态温升可控。
  • 布局要点:缩短高电流回路(输入电容—开关节点—电感—输出电容)环路,减小开关节点走线长度与环路面积,独立模拟/功率地以降低噪声耦合。
  • EMI 控制:启用抖频模式并配合输入滤波,必要时在开关节点增加 RC 缓冲或共模滤波器。

六、封装与可靠性

  • 封装:QFN-20(4×4),便于自动贴装与散热设计。
  • 可靠性:器件工作温度覆盖宽温区(-40℃ ~ +150℃)并提供短路保护、热关断等多重保护机制,适合工业与车载应用。

该器件集成度高、功能完善,适合对体积、效率与 EMI 有严格要求的中高功率降压场景。选型时建议结合目标输入/输出范围、最大纹波、热预算与 PCB 版型进行仿真与样板验证。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
