TMI3113H2 产品概述
一、产品简介
TMI3113H2 是拓尔微（TMI）推出的一款降压型同步整流开关稳压器，工作电压范围 2.7V～5.5V，内置开关管，最高输出电流 3A，开关频率 1.5MHz，适用于对体积与效率有较高要求的电源设计。器件工作结温范围为 -40℃～+125℃，静态电流仅 50µA，适合移动与便携应用的休眠/低功耗场景。
二、主要参数
- 功能类型：降压型（同步整流）
- 输入电压：2.7V ～ 5.5V
- 输出电流：最大 3A
- 开关频率：1.5MHz
- 同步整流：内置（是）
- 输出通道：单路、可调输出
- 静态电流：50µA
- 开关管：内置
- 封装：SOT-23-6
- 工作温度：-40℃ ～ +125℃（TJ）
三、核心优势
- 高频工作（1.5MHz）有利于减小电感与输出滤波体积，便于小型化布局；
- 同步整流与内置开关管提高轻载至重载效率，减少外部元件复杂度；
- 低静态电流适合需要低待机功耗的电池供电设备；
- 宽工作电压与高温等级满足多种工业与消费类应用环境。
四、典型应用
- 移动设备与可穿戴设备的电源模块
- 无线通信终端、蓝牙耳机、IoT 传感器节点
- 工业控制与车载电子（非完整车规级）中的局部稳压
- 模块化电源、后备电源与驱动供电
五、设计与布局建议
- 高频下推荐使用低 ESR 陶瓷电容（X5R/X7R），输入输出侧各至少 10µF～22µF；考虑高频纹波，适当并联小容量以改善高频特性；
- 电感选择饱和电流大于 3A 的型号，典型电感量可在 0.47µH～1.5µH 范围内取舍，按输出纹波与效率权衡；
- 布局要点：VIN、GND、开关节点走线尽量短且宽，输入旁路电容靠近 VIN 和 GND 引脚摆放，开关节点铜皮尽量缩小以降低辐射；
- 热管理：SOT-23-6 封装需注意 PCB 散热，必要时增加铜箔面积或散热通孔以便导热。
如需参考典型应用电路、外部元器件选型表或效率/纹波测试曲线，可提供更详细的设计资料与 PCB 布局范例。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
