TMI3113H2D 是拓尔微(TMI)推出的一款降压型同步整流开关稳压器,采用降压拓扑、内置功率开关,适用于对体积和效率有要求的电源设计。器件工作电压范围为 2.7V 至 5.5V,输出可调范围为 600mV 至 5.5V,最大输出电流可达 3A,开关频率 1.5MHz,静态电流仅 50μA,工作温度范围 -40℃ 到 +85℃(TA),单通道输出,封装为 DFN-8-EP(2×2)。
TMI3113H2D 以 600mV 作为内部参考(最小可调输出即为 600mV),通过外部分压电阻设定期望输出电压。内置高、低侧开关,器件在中高负载时能保持高转换效率;在轻载情况下低 Iq 有助于延长电池寿命。请注意器件的热限和 PCB 热阻会影响持续输出能力,需结合实际散热评估。
DFN-8-EP (2×2) 小体积利于紧凑布局,但需将底部热焊盘完整焊接至 PCB 大面积散热铜箔,并配置过孔通向多层内/底层铜箔以降低结壳热阻。3A 输出条件下,建议在评估散热及环境温度后确认降额使用或增加散热路径。
TMI3113H2D 以其高开关频率、小尺寸封装、低静态电流与同步整流优势,适合对体积与效率敏感的单路降压电源设计。实际设计请结合厂方数据手册与 PCB 热仿真,确保满足可靠性与性能要求。

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.
