RT8097AHGB 降压型DC-DC电源芯片产品概述

一、产品核心定位

RT8097AHGB是台湾立锜(RICHTEK)推出的同步降压型DC-DC电源芯片,专为空间受限、低功耗需求的便携及IoT设备设计。其采用超小型SOT-23-5封装,内置同步整流管与功率开关管,可实现宽电压范围的高效降压转换,兼顾小体积与中电流输出能力,是电池供电设备的理想电源解决方案。

二、关键电气特性

RT8097AHGB的电气参数覆盖主流便携设备需求,核心特性如下:

  1. 输入输出范围:输入电压支持2.7V6V(兼容3.7V锂电池、3V干电池、5V USB电源);输出电压通过外部电阻分压可调,范围600mV3.4V,适配低电压MCU、传感器、无线模块等负载。
  2. 电流与功耗:连续输出电流达2A,满足中小功率负载;静态电流仅22uA,大幅降低待机电池消耗,延长设备续航。
  3. 频率与效率:固定1MHz开关频率,可减小电感/电容体积;内置同步整流管,典型负载效率超90%,减少发热。
  4. 环境适应性:工作温度-40℃~+85℃(环境温度TA),符合工业级要求,极端环境下稳定工作。
  5. 集成度:内置功率开关管与同步整流管,无需外部功率器件,简化电路设计。

三、封装与引脚配置

RT8097AHGB采用SOT-23-5超小型封装(尺寸2.9mm×2.5mm×1.1mm),适合高密度PCB布局,引脚功能明确:

  • Pin1(VIN):电源输入,需接1μF陶瓷滤波电容;
  • Pin2(GND):接地,需可靠连接PCB地平面;
  • Pin3(FB):反馈引脚,通过分压电阻设置输出电压(FB固定0.6V);
  • Pin4(SW):开关节点,接电感与内置同步整流管;
  • Pin5(VOUT):电源输出,需接2.2μF陶瓷滤波电容。

四、典型应用场景

RT8097AHGB适配多种便携及工业应用:

  1. 便携消费电子:蓝牙耳机、智能手环、智能手表、便携式音箱(3.7V锂电池输入,驱动MCU、蓝牙模块);
  2. IoT终端:低功耗传感器节点、小型智能插座、智能家居控制模块(低静态电流适合长期待机);
  3. 工业辅助设备:小型工业传感器、手持测试仪器、车载辅助设备(宽温与宽电压输入);
  4. 小型电源模块:USB转低电压电源、电池供电辅助电源(灵活输出调节)。

五、产品优势总结

与同类产品相比,RT8097AHGB核心优势突出:

  1. 小封装大电流:SOT-23-5封装实现2A连续输出,体积与电流比优秀;
  2. 低功耗待机:22uA静态电流,智能手环等设备待机时间可提升30%以上;
  3. 宽电压适配:输入2.7V6V、输出0.6V3.4V,覆盖纽扣电池到锂电池的多种电源;
  4. 高效率低发热:同步整流效率超90%,2A输出时温升低,适合密集布局;
  5. 设计简单:仅需少量外部元件(电感、电容、分压电阻),缩短开发周期。

六、使用注意事项

为保证稳定工作,需注意:

  1. 元件选择:FB分压电阻用1%精度金属膜电阻;电感选1.5~2.2μH功率电感;电容用低ESR陶瓷电容(X7R材质);
  2. PCB布局:输入/输出电容靠近引脚放置,减少噪声;FB分压电阻靠近FB引脚,避免长走线干扰;
  3. 散热:2A连续输出或85℃环境下,增加VIN/VOUT引脚铜箔面积辅助散热;
  4. 输出设置:VOUT=0.6V×(1+Rtop/Rbottom),Rtop接VOUT,Rbottom接GND。

RT8097AHGB凭借小体积、低功耗、高效率的特点,成为便携设备与IoT终端的高性价比电源选择。

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.

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
