MPQ2172GJ-AEC1-Z 是 MPS(Monolithic Power Systems)推出的一款高开关频率、同步整流的降压型开关稳压器,面向对体积、效率与汽车级可靠性有高要求的系统设计。器件工作输入电压范围为 2.5V ~ 5.5V,输出电压可调范围为 0.6V ~ 5.0V,最大连续输出电流 2A。器件采用内置开关管和同步整流结构,开关频率为 2.6MHz,封装为 TSOT-23-8,器件设计满足汽车级工况(工作结温 TJ 可达 +150℃@TJ),适合点对点降压、MCU/系统电源及车用电子电源前端等应用。
MPQ2172GJ-AEC1-Z 将功率开关(高侧、低侧 MOSFET)集成在芯片内部,实现完整的降压拓扑输出。器件通过固定高频开关控制输出电压,在外接反馈网络(外置电阻)设定目标输出后稳定工作。为了保证系统安全与可靠性,器件集成了多重保护:
器件采用 TSOT-23-8 小型封装,便于在受限空间内进行 PCB 布局。由于器件可在高达 +150℃ 的结温下工作,实际应用中仍需关注功率损耗与散热条件:
总结:MPQ2172GJ-AEC1-Z 以 2.6MHz 的高开关频率、同步整流与汽车级可靠性为核心优势,适合要求小体积、高效率、智能保护与工业/车规级工作的降压电源设计。若需针对具体应用的典型电路、元件清单或热设计建议,可提供系统输入电压、目标输出电压及 PCB 约束信息以便进一步优化。

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.
