ME2108C33M5G 产品概述

一、产品简介

ME2108C33M5G 是 MICRONE(南京微盟)推出的一款升压型 DC-DC 转换器,采用 SOT-23-5 小型封装,针对空间受限的电源设计提供 3.3V 固定输出。芯片内置开关管,工作电压范围宽(0.9V~6.5V),可在单节低压电池或其他低压电源下升压至稳定的 3.3V 输出,适合便携式、物联网与传感器节点等应用。

二、主要电气参数

  • 功能类型:升压(Boost)
  • 输入电压 VIN:0.9V ~ 6.5V
  • 输出电压 VOUT:固定 3.3V
  • 输出电流 IOUT:最高可达 400mA
  • 开关频率:约 180kHz
  • 静态电流 Iq:约 50µA(低静态功耗)
  • 同步整流:否(需外接肖特基二极管)
  • 工作温度范围:-25℃ ~ +85℃(TA)
  • 封装:SOT-23-5
  • 拓扑结构:升压式,内置开关管,单通道输出

三、性能亮点

  • 低启动电压:0.9V 起能够工作,适用于单节电池或低电压能源回收场景;
  • 低静态电流:典型待机电流约 50µA,有利于延长电池寿命的低功耗设备;
  • 小封装:SOT-23-5 封装便于空间受限的终端产品集成;
  • 固定输出:3.3V 输出简化外部反馈网络,便于快速上手设计。

四、典型应用与选型建议

  • 便携式设备、可穿戴与手持终端;
  • 物联网节点、无线传感器、遥控设备;
  • 需要从 1 节或多节低压电源升压到 3.3V 的场景。 选型时注意输出 400mA 为最大级别,在输入电压极低或负载接近峰值时,电感、电流应力和热耗较大,需在实际工况下验证效率与温升。

五、参考外部元件与常见应用电路

由于为非同步整流结构,必须外接肖特基整流二极管以降低损耗。典型外部元件建议(仅供参考,需按数据手册计算):

  • 电感 L:4.7µH ~ 22µH,根据输入电压与输出电流选型,保证电感不饱和;
  • 肖特基二极管:1A 以上、低正向压降型号(如 SS3x/SS14/SS34 类);
  • 输入电容:10µF ~ 47µF 低 ESR 电解或陶瓷;
  • 输出电容:22µF ~ 100µF 低 ESR 陶瓷或固态电容,保证输出纹波与瞬态响应。 常见应用电路包含 VIN、GND、SW 引脚与电感、二极管、输出电容的标准升压连接,EN(或使能)引脚用于开/关控制。

六、PCB 布局与热管理

  • 将电感、二极管、输入/输出电容尽量放置在芯片附近,缩短高电流回路;
  • SW 引脚走线尽可能短且宽,减少 EMI 与功率损耗;
  • GND 采用完整铜箔回流,必要时在芯片下方连通散热区域以利散热;
  • 在满载或高环境温度下评估功耗与温升,必要时加大散热空间或采用热沉/散热铜箔。

七、封装与可靠性

SOT-23-5 小封装利于贴片生产与空间受限设计。出货前建议参考 MICRONE 的完整数据手册和典型电路进行设计验证,关注过温保护、过流条件与长期可靠性测试要求,确保在目标工作温度范围内稳定运行。

注:以上为产品概述与设计建议,具体电气特性、引脚定义与应用电路请以官方数据手册为准。

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
