LT1930ES5#TRPBF DC-DC电源芯片产品概述

LT1930ES5#TRPBF是亚德诺半导体(ADI,原LINEAR)推出的一款多拓扑可调DC-DC电源芯片,主打小体积、灵活适配与稳定输出,广泛应用于便携电子、低功耗工业模块等场景。以下从核心特性、电气指标、应用场景等维度展开详细说明。

一、核心功能与拓扑特性

该芯片为升压型为主的多拓扑兼容器件,支持三大核心拓扑结构,适配不同输入输出场景:

  1. 升压拓扑:输入电压低于输出时,实现高效升压转换,满足“低输入→高输出”需求(如单节锂电池升压至5V);
  2. SEPIC(单端初级电感转换器):输入电压可低于、等于或高于输出电压(典型如电池供电场景,电池从满电3.7V降至2.5V时,仍能稳定输出3.3V),是升降压应用的理想选择;
  3. 反激拓扑:支持隔离式小功率输出,适配需要电气隔离的低功耗场景(如部分医疗传感器、工业控制模块)。

此外,芯片内置高压开关管,无需外置功率管,简化电路设计;采用异步整流(无内置同步整流管),兼顾效率与成本,适合对效率要求非极致但空间敏感的应用。

二、电气参数关键指标

LT1930ES5#TRPBF的电气参数覆盖宽输入输出范围,适配多数小功率电源需求:

  • 输入电压范围:2.6V16V,兼容单节锂电池(2.4V4.2V)、多节干电池(3V~12V)及低电压直流电源,覆盖便携与低功耗工业场景;
  • 输出电压范围:2.45V~36V(可调),通过外部电阻分压可精准设置输出电压,满足从3.3V微控制器供电到12V/24V小功率负载的需求;
  • 输出电流能力:1A(典型值),支持多数便携设备(如蓝牙音箱、智能手环)及小型传感器模块的功率需求;
  • 开关频率:1.2MHz(固定),高频设计使电感、电容等被动元件可选用小封装(如10μH以下电感),大幅节省PCB面积;
  • 静态电流:6mA(典型值),低静态电流适合电池供电设备,延长单次充电续航时间;
  • 工作温度范围:0℃~+70℃(商业级),适配室内、常规便携设备的温度环境。

三、封装与典型应用场景

该芯片采用TSOT-23-5封装(超小型表面贴装),尺寸仅约2.9mm×1.6mm×1.1mm,是同类产品中体积极小的方案之一,适合空间受限的便携设备与高密度PCB设计。

典型应用场景包括:

  1. 便携电子设备:蓝牙音箱、智能手环、MP3播放器、便携式医疗设备(如血糖仪)等,利用其宽输入范围与小体积适配电池供电;
  2. 物联网(IoT)节点:低功耗传感器模块(如温湿度、运动传感器),SEPIC拓扑可在电池电压波动时保持稳定输出;
  3. 工业低功耗模块:小型控制单元、数据采集模块,反激拓扑可实现隔离供电,提升系统抗干扰能力;
  4. 消费电子配件:手机充电宝升压模块、无线充电器辅助电源等。

四、品牌与可靠性优势

作为ADI(亚德诺)旗下LINEAR系列产品,LT1930ES5#TRPBF继承了工业级品质优势:

  • 稳定性与一致性:ADI严格的生产工艺确保芯片参数一致性,减少批量应用中的调试难度;
  • 设计简化:内置开关管+多拓扑兼容,仅需少量外部元件(电感、电容、电阻)即可实现电源转换,降低BOM成本与设计周期;
  • 散热适配:TSOT-23-5封装虽小,但1A输出功率下散热性能满足商业级应用需求,无需额外散热设计。

综上,LT1930ES5#TRPBF以小体积、多拓扑、宽输入输出范围为核心优势,适配便携电子、IoT节点、低功耗工业模块等场景,是一款高性价比的可调DC-DC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
