MP28167GQ-Z 是一款面向广泛工业与便携应用的单通道升降压稳压器,采用降压-升压拓扑并集成同步整流与功率开关,能在输入电压高于或低于目标 5V 时保持稳定输出。500 kHz 的工作频率在保持效率与外围元件体积之间取得了平衡,内置开关减少了外部元件复杂度,静态电流低至约 1 mA,适合对待机功耗有要求的系统。
QFN-16 (3×3 mm) 小体积有利于紧凑系统设计,但热量集中,建议焊接暴露焊盘并与大面积 PCB 铜箔相连以提升导热能力,保证在 3A 输出时的可靠性。
MP28167GQ-Z 提供了在 2.8V–22V 输入下稳定 5V/3A 输出的紧凑方案,内置开关与同步整流简化外部设计,低静态电流适合低功耗场景。针对最终应用请参阅原厂数据手册获取典型参考电路、元件值和完整保护特性,并按应用工况优化布局与散热设计。

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.
