TMI3101C 是拓尔微(TMI)推出的一款降压型(Buck)同步整流DC-DC转换器,面向空间受限、对效率和静态功耗有严格要求的电池供电与便携类应用。器件内置功率开关,工作电压范围宽,开关频率高,支持可调输出,整体集成度高、外围元件少,适合做单通道1A电源轨。
SOT-23-5 封装在高输出电流或高输入电压差时会产生较大功耗,需关注PCB铜箔散热、加大GND层面积并考虑热沉路径。工作环境接近极限温度时,应评估长期热应力对输出稳定性的影响并留有裕量。
总结:TMI3101C 以其高集成度、低静态电流及高开关频率,适合对体积与能耗敏感的便携与物联网设备,能在保证效率的同时显著减小电源模块尺寸。设计时关注布局、滤波与散热即可发挥其最佳性能。

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.
