MPM3834CGPA-Z 产品概述

一、产品简介

MPM3834CGPA-Z(MPS)是一款降压型电源管理模块,输入电压范围2.75V至6V,输出电压可设定在0.60V至6.00V,最大输出电流3A。该模块采用ECLGA-14封装(2.5mm×2.5mm),高度1.2mm,体积超小,适合空间受限的便携与嵌入式系统。工作温度范围为-40℃至+125℃,集成多重保护,适用于对稳定性和可靠性要求高的点对点电源设计。

二、核心性能

  • 输入电压:2.75V ~ 6V
  • 输出电压:0.60V ~ 6.00V(可调)
  • 最大输出电流:3A
  • 转换效率:高达85%(典型条件下)
  • 开关频率:1.25MHz(典型),便于选用小型电感与电容
  • 纹波噪声:典型8mVp‑p
  • 静态电流(Iq):约500µA,利于低功耗待机设计

三、保护与可靠性

模块集成:

  • 过流保护(OCP) —— 限制峰值电流,保护器件与负载
  • 短路保护(SCP) —— 在输出短路时自动进入保护状态
  • 过热保护(OTP) —— 温度异常时关闭或降额以防损坏
    这些保护机制提升了系统的安全性与长期可靠性,适合工业级与汽车类等严苛环境使用。

四、封装与热管理

  • 封装:ECLGA-14 (2.5mm × 2.5mm)
  • 尺寸:长2.5mm、宽2.5mm、高1.2mm
    紧凑封装有利于高密度板级集成。建议在PCB上配合较大散热焊盘和多层接地平面以改善热传导与温升管理,确保在3A输出下的稳定工作。

五、典型应用场景

  • 手持设备与便携终端电源
  • 物联网节点与无线通信模组(点对点供电)
  • 可穿戴设备与传感器供电
  • 工业控制与嵌入式系统的局部稳压电源

六、设计与布局建议

  • 开关频率1.25MHz允许使用体积小的电感(根据电流与效率选择)和低ESR电容以抑制纹波。
  • 输入侧尽量靠近模块布置去耦电容,缩短走线,降低回路面积。
  • 地线采用焊盘与多层地平面相连,热焊盘与通过孔有助于散热。
  • 输出反馈网络需按应用要求精确设计,以确保输出精度与稳定性。
  • 在高电流工作状态下验证PCB温升,必要时采取铜厚、散热板或散热片等额外散热措施。

七、器件信息与订购

  • 型号:MPM3834CGPA-Z
  • 品牌:MPS(Monolithic Power Systems)
    在选型时请参考厂商完整数据手册与评估板资料,按照实际负载与环境条件验证效率、纹波和热性能,确保设计长期稳定。

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
