MPQ2178GQHE-AEC1-Z 是 MPS 提供的一款高频降压型 DC-DC 转换器,输入电压范围 2.5V 至 5.5V,输出电压可调 600mV 至 5V,最大输出电流 2A。芯片集成开关管(降压拓扑)、采用非同步整流结构,开关频率高达 2.4MHz,封装为 QFN-8 (1.5×2mm),适合空间受限且对轻载效率和快速瞬态有要求的便携式与工业类应用。
芯片采用 QFN-8 (1.5×2mm) 小尺寸封装,利于密集布局与热传导。常见外部器件包括电感、输入/输出陶瓷电容、反馈分压电阻、软启动电容和限流相关器件。具体引脚功能与推荐 PCB 布局请参照官方数据手册与参考电路。
在选型阶段,如需高效率、低静态电流并且要求小尺寸封装,MPQ2178GQHE-AEC1-Z 是较优选择。建议在样片评估时关注:轻载效率曲线、过载/短路响应、热升温特性及在目标 PCB 上的瞬态输出电压跌落与恢复情况。最终设计请以 MPS 正式数据手册与参考设计为准。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
