MPQ4436AGRE-AEC1-Z 产品概述

一、概述

MPQ4436AGRE-AEC1-Z 是美信(MPS)推出的一款高集成度降压型同步整流 DC-DC 控制器/电源芯片,封装为 QFN-20 (4x4)。芯片集成高侧/低侧开关管,支持单路输出、输出可调(参考电压约 815mV),输入工作电压宽泛(3.3V ~ 45V),输出电流最高可达 6A,适合对体积、效率和温度要求较高的点对点供电场合,且满足汽车级工作温度(-40℃ ~ +150℃ @ TJ)。

二、主要特性

  • 降压拓扑,内置功率开关管,减小外部器件数量和 PCB 面积。
  • 输入电压范围宽:3.3V ~ 45V;输出电压可调:0.815V ~ 45V。
  • 连续导通或断续模式下都能高效工作,同步整流提高轻载到重载的转换效率。
  • 开关频率可在 350kHz ~ 1MHz 范围调整,支持外部频率同步,便于多路系统并行与 EMI 管理。
  • 极低静态电流 Iq ≈ 18µA,利于电池供电或待机低功耗场景。
  • 具备轻载高效模式、可调软启动、抖频(Spread-Spectrum)EMI 优化、工作状态指示与打嗝限流等实用功能。

三、可靠性与封装

  • 封装:QFN-20 (4x4),带底部散热焊盘,便于热量传导与 PCB 散热设计。
  • 工作结温范围宽(-40℃ ~ +150℃)使其适合汽车电子与工业级应用。
  • 内建保护与限流策略(打嗝模式)提高系统在短路或过载时的自恢复能力。

四、典型应用场景

适用于汽车车载电子(ECU、传感器供电、车载网关)、工业自动化、通信设备、摄像头/影像模块、嵌入式主控点对点电源以及其他需宽 Vin、单路 6A 级稳压电源的场合。

五、设计要点建议

  • 外部功率器件:选择额定电流和饱和电流高于峰值电流的电感,低 ESR 输出电容以降低纹波并提升瞬态响应。
  • 布局:尽量靠近芯片布局输入/输出电容与开关走线,底部大焊盘与多via用于散热。
  • EMI:开启抖频模式并选择合适开关频率可降低电磁干扰,必要时配合滤波网络。
  • 多路同步:使用频率同步功能以避免相互干扰并优化系统 EMI。

如需原理图参考、典型应用电路或物料清单(BOM)建议,可提供系统参数(Vin、Vout、最大负载与环境条件)以便给出更具体的设计方案。

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
