TPS61040M5/TR 产品概述

TPS61040M5/TR(华冠 HGSEMI 兼容型号)是一款升压型 DC-DC 转换器,面向低功耗便携类电源应用。器件采用 SOT-23-5 封装,内部集成开关管,工作频率为 1MHz,输入电压范围宽(1.8V ~ 6V),并提供可调输出,极适合通过小外形电感与陶瓷电容实现高密度电源设计。

一、主要参数概览

  • 功能类型:升压型(Boost)
  • 输入电压:1.8V ~ 6V
  • 开关频率:1MHz(高频,利于小型无源件)
  • 输出通道数:单通道,可调输出
  • 拓扑结构:升压式
  • 静态电流(Iq):约 28µA(低待机功耗)
  • 开关管:内部集成(简化外形与布局)
  • 工作温度:-40℃ ~ +125℃
  • 封装:SOT-23-5
  • 品牌:HGSEMI(华冠)

二、功能与优势

  • 低静态电流:待机电流约 28µA,适合电池供电、长待机的物联网与便携设备。
  • 高频开关:1MHz 工作频率允许使用较小体积的电感和陶瓷电容,降低整体 PCB 面积和 BOM 体积。
  • 内置开关管:减少外部器件数目,简化电路设计与布局。
  • 宽输入范围与高温工作:支持常见锂电与干电池供电,并能在工业级温度范围内稳定工作。

三、典型应用场景

  • 可穿戴设备与健康监测终端
  • 低功耗物联网节点、无线传感器
  • 便携式仪器、电池供电的小型消费电子
  • LCD/显示背光、白光 LED 队列(需配合限流或恒流电路)
  • 电池电压提升至 MCU、传感器或射频模块所需电压

四、设计与布局建议

  • 外部电感:由于 1MHz 高频率,优先选用低 DCR、饱和电流高于峰值电流的功率电感;体积可选低至几 µH。
  • 输入/输出电容:使用低 ESR 陶瓷电容,输入端靠近 VIN 与 GND 引脚放置,减小回流环路。输出端陶瓷电容值应满足滤波与稳定性要求。
  • 开关节点(SW)走线要尽量短且宽,减少 EMI。GND 采用完整地平面,感性元件与电容形成最短回路。
  • 热管理:SOT-23-5 封装热阻有限,高输出电流时注意 PCB 铜箔散热与器件间距设计。
  • 输出电压调整:通过外接分压电阻设置所需输出电压,选择阻值时兼顾功耗与稳定性。

五、可靠性与开发提示

  • 在 1MHz 工作频率下,注意 EMI 测试与滤波设计,必要时加小型共模或差模滤波器。
  • 对于电池掉电或输入瞬变,建议在输入端增加合适的瞬态抑制与滤波元件以保护芯片。
  • 在系统选型时,核算最大开关电流、占空比及功率损耗,验证在最高工作温度下的稳态效率与热升。

六、小结

TPS61040M5/TR 是一款针对低功耗、空间受限应用的高频升压转换器,优势在于内置开关、低静态电流与宽输入电压范围。通过合理选择外部电感、电容与良好的 PCB 布局,可在便携与物联网终端中实现稳定高效的升压电源解决方案。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
