LTC3260EMSE#TRPBF 产品概述

LTC3260EMSE#TRPBF是亚德诺(ADI)旗下的一款充电泵型DC-DC电源转换芯片,专为小功率、低EMI、宽环境适应性的电源设计需求打造。该芯片无电感、无变压器设计,结合宽电压输入范围与可调输出特性,广泛适用于工业、汽车、便携式设备等场景。

一、核心拓扑与功能定位

LTC3260采用充电泵拓扑(电荷泵),区别于传统电感式DC-DC:无需外接电感/变压器,仅需少量电容即可实现电压转换,大幅降低PCB体积与系统EMI(电磁干扰)。其核心功能为将输入电压转换为可调输出电压,最大输出电流100mA,满足小功率负载(如传感器、MCU外设、低功耗通信模块等)的供电需求。

二、关键电气参数解析

1. 宽范围输入电压

输入电压覆盖4.5V~32V,兼容多种电源场景:

  • 便携式设备:单节锂电池(放电至4.5V以上)、多节干电池;
  • 工业/汽车:12V(汽车蓄电池)、24V(工业PLC电源)、30V以下直流电源;
  • 抗波动能力:宽输入范围可适应电源电压波动(如汽车启动时的电压跌落)。

2. 可调输出与负载能力

输出电压连续可调(需外接电阻分压设定),最大输出电流100mA,可满足:

  • 低功耗MCU(如STM32L系列)的3.3V/1.8V供电;
  • 模拟传感器(如压力、温度传感器)的5V/3.3V供电;
  • 小型通信模块(如蓝牙低功耗模块)的供电需求。

3. 灵活开关频率

开关频率范围50kHz~500kHz,可通过外接电阻调整:

  • 低频(50kHz):降低开关损耗,提升效率;
  • 高频(500kHz):减小外接电容体积,适合高密度PCB;
  • 抗干扰优化:可根据实际应用的噪声频段调整频率,避免系统干扰。

4. 宽温度适应性

工作结温范围**-40℃125℃**,满足工业级(-4085℃)与汽车级(-40~125℃)环境要求:

  • 低温场景:汽车冬季低温启动、户外工业传感器;
  • 高温场景:汽车发动机舱、工业控制柜内的高温环境。

三、封装与热管理设计

LTC3260EMSE#TRPBF采用16-MSOP-EP(裸露焊盘)封装:

  • 物理尺寸:3.00mm宽、0.118英寸(3.00mm)脚距,体积紧凑,适合高密度PCB布局;
  • 裸露焊盘(EP):直接连接芯片内部散热层,提升热传导效率,降低结温,确保宽温下稳定工作;
  • 表面贴装型:兼容自动化贴装产线,降低生产难度。

四、典型应用场景

1. 汽车电子

  • 胎压监测系统(TPMS):宽温范围适应-40℃低温与轮胎内高温,无电感设计避免对传感器的电磁干扰;
  • 车身传感器(如车门开关、温度传感器):12V输入兼容汽车蓄电池,可调输出匹配传感器供电。

2. 工业控制

  • PLC模拟量模块:24V输入兼容工业电源,低EMI避免对模拟信号的干扰;
  • 户外传感器节点:-40℃~85℃宽温适应户外环境,小体积适合节点集成。

3. 便携式设备

  • 手持医疗仪器(如血糖仪、血压计):小封装节省空间,宽输入兼容锂电池;
  • 低功耗蓝牙设备:100mA输出满足模块供电,无电感降低设备重量。

五、产品优势总结

  1. 低EMI设计:充电泵拓扑无电感,减少电磁辐射,适合对EMI敏感的医疗、通信场景;
  2. 宽电压适配:4.5V~32V输入覆盖绝大多数直流电源,无需额外电源转换;
  3. 灵活可调:输出电压连续可调,开关频率可配置,适配多种负载需求;
  4. 宽温可靠:-40℃~125℃结温,满足工业与汽车级恶劣环境;
  5. 小体积集成:MSOP-16-EP封装,裸露焊盘提升散热,适合高密度设计。

作为ADI的成熟电源芯片,LTC3260EMSE#TRPBF凭借其拓扑优势与宽参数范围,成为小功率电源设计的高性价比选择,尤其适合对体积、EMI、环境适应性要求严格的场景。

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
