MP8128GQ-Z 是 MPS 面向卫星接收前端(LNB)供电设计的开关稳压器,输出电流可达 1A,集成 I2C 接口和 DiSEqC 2.x 功能。器件在满足 LNB 电源需求的同时,提供丰富的保护与控制能力,适合机顶盒、卫星接收器、头端设备等对 LNB 供电与控制要求较高的应用场景。封装为 QFN-20 (3×3),利于系统级集成和散热。
MP8128GQ-Z 的 QFN-20 (3×3) 便于高密度布局,但对焊接与散热要求较高。建议在 PCB 底部设计足够的热铜箔与过孔,并参考器件数据手册的典型布局示意,保证电源回路短且宽,信号线远离高电流回路。
MP8128GQ-Z 将可编程限流、状态监测、输出放电与过流保护等功能与 I2C/DiSEqC 控制集成在小型 QFN 封装中,适合对 LNB 供电与控制有较高可靠性与可管理性要求的卫星接收设备。通过合理的布局、滤波与参数配置,可在保证性能的同时提升系统的稳定性与安全性。

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.
