MPQ2166GD-AEC1-Z 是 MPS 提供的一款双通道降压型开关稳压器,面向要求体积小、效率高且具备汽车级工作温度特性的电源管理应用。器件集成同步整流开关管,支持高达 3MHz 的开关频率,输入电压范围覆盖 2.7V 至 6V,输出电压可通过外部电阻调整在 600mV 至 5.5V 之间。器件命名中的 AEC1 表明其面向汽车级或工业级严苛工作环境设计,工作结温范围为 -40℃ 至 +125℃ (TJ)。
MPQ2166GD-AEC1-Z 采用 QFN-18(2×3 mm)小尺寸封装,利于高密度 PCB 设计。QFN 封装通常带有底部散热焊盘,应在 PCB 布局中提供充分的热沉铜箔与多层过孔以提升导热能力,确保在高负载或高环境温度下仍能维持稳定工作。
器件集成逐波限流与打嗝限流机制,可在短路与持续过载情况下提供自恢复保护,配合可调软启动与状态指示进一步提升系统鲁棒性。工作温度范围及封装形式适合较宽温度变化环境,但在最终产品设计中仍应进行热分析与长时间可靠性测试以满足整车/系统的生命周期要求。
MPQ2166GD-AEC1-Z 适合需要双路、小体积、低静态电流且具备汽车级温度要求的降压点负载应用。3MHz 的高开关频率与内部同步 MOSFET 的集成,使其在空间受限的系统中能采用更小的电感与电容。设计时应根据负载电流等级(1A/2A/3A 版本)与热散能力选择合适封装和 PCB 布局,并结合器件手册推荐的外围元件值完成稳定可靠的电源设计。若需进一步的电路示例、布局示意或器件手册中详细参数建议参考 MPS 官方资料与评估板设计指南。

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.
