TS30042-M050QFNR 是 SEMTECH 提供的一款降压型开关稳压器(同步整流、固定输出),采用 WQFN-16-EP (3×3 mm) 封装并带裸露焊盘,面向需要稳定 5.0V 输出且输入电压范围宽的应用场景。器件内置开关管,单输出通道,最高输出电流可达 2A,开关频率为 900kHz~1.1MHz,静态工作电流仅 3.6mA,工作温度范围为 -40℃~+125℃。
适用于工业控制、电信设备、嵌入式系统、电源模块与其它需从较宽输入获得稳定 5V/2A 电源的场合。高开关频率和小封装使其也适合空间受限且对 EMI 管理有要求的设计。
WQFN-16-EP 封装需注意焊盘焊接工艺与回流温度曲线,暴露焊盘需与 PCB 地平面良好焊接并配置散热过孔以满足 -40℃~+125℃ 的工作温度要求。建议参照 SEMTECH 的 PCB 推荐焊盘与回流规范以获得最佳热性能与机械可靠性。
TS30042-M050QFNR 提供了宽输入、低静态电流、高开关频率与同步整流等优势,适合体积受限且需高效率 5V/2A 输出的电源设计。合理选择电感、电容并优化 PCB 布局与裸露焊盘散热,可在保证稳定性的前提下实现高能效与良好热管理。若需更详细的电气特性表、引脚定义或参考电路,请参阅厂商数据手册。

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.
