MPQ4323GDE-AEC1-Z 产品概述
一、概述
MPQ4323GDE-AEC1-Z 是 MPS 提供的一款高集成度降压型开关稳压器，面向汽车及工业应用。器件支持 3.3V36V 宽输入电压并具备 42V 抗负载冲击（load dump）能力，内部集成开关管和同步整流，最大输出电流可达 3A，输出电压可通过外部分压器调节。工作结温可达 -40℃+150℃，适合严苛环境工作。
二、主要规格
- 功能类型：降压（Buck）
- 输入电压：3.3V ~ 36V（支持 42V load dump）
- 输出电流：最大 3A
- 开关频率：可设 350kHz ~ 2.5MHz
- 静态电流：Iq ≈ 20 μA（低静态电流，利于待机节能）
- 同步整流：内置（提高效率、降低外部二极管需求）
- 输出通道：单路，可调输出
- 开关管：内置功率 MOSFET
- 封装：QFN-12 (2x3)
- 工作温度：-40℃ ~ +150℃@TJ
三、器件特点与优势
- 宽电压输入与高电压冲击耐受，满足汽车 12V/24V 系统的瞬态要求；
- 高集成度减少外部元件数，适合空间受限的车载系统；
- 可变开关频率范围允许在效率与尺寸之间权衡（高频可减小电感和输出电容）；
- 20 μA 的低静态电流适用于待机或低功耗场景；
- QFN-12 紧凑封装利于高密度 PCB 布局。
四、设计建议与注意事项
- 输入端采用低 ESR 电容，靠近器件放置以抑制瞬态尖峰并承受 load dump；
- 根据工作频率与输出电流选择合适电感（饱和电流 >3A 且低 DCR 有利于效率）；
- 输出滤波器电容需兼顾纹波、瞬态响应与升温特性；
- 布局上应保证电流回路短且宽，热量通过铜箔和地平面散出；
- 可调输出通过外部分压实现，注意补偿与稳态误差。
五、典型应用
车载电子（ECU、仪表、车载网关）、工业供电模块、通信设备及需宽输入容错能力的便携或嵌入式系统。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
