ME2107A50M5G 产品概述

一、概述

ME2107A50M5G 是南京微盟(MICRONE)推出的一颗升压型 DC-DC 开关稳压器,输入电压范围宽(900mV ~ 5.5V),输出为固定 5.0V,最大输出电流 300mA。芯片内部集成开关管并采用同步整流拓扑,静态电流仅 7.5µA,适用于单节电池或低电压电源启动并稳定升压到 5V 的便携与低功耗系统。封装为 SOT-23-5,工作温度 -40℃~+85℃,开关频率约 320kHz。

二、主要特点

  • 输入启动电压低,最低可在 0.9V 启动,适合单节电池或干电池供电场景。
  • 固定 5V 输出,最大持续输出 300mA,内部同步整流提高效率且无需外部肖特基二极管。
  • 极低静态电流(Iq = 7.5µA),利于电池寿命延长与待机应用。
  • 开关频率 320kHz,在体积与效率间取得平衡,有利于使用小体积电感与电容。
  • SOT-23-5 小封装,适合体积受限的终端产品。

三、典型应用

  • 便携式传感器、无线节点、蓝牙设备、可穿戴设备;
  • 单节电池驱动的 MCU 与传感器供电;
  • 小型手持工具、仪表、低功耗 IoT 终端。

四、设计与选型建议

  • 电感:选择饱和电流高于峰值电流的屏蔽功率电感,常见范围 4.7µH~22µH,DCR 尽量低以减少损耗;
  • 输入/输出电容:建议使用 X7R 陶瓷电容,输入端 10µF 且并联 0.1µF 陶瓷去耦,输出端 22µF~47µF 以保证负载瞬态响应;
  • 由于为同步整流,通常无需外部肖特基;若需防止输出回灌,可在输出侧加微安级反向保护措施。
  • 为实现最佳效率与稳定性,请根据负载与线路调试回路补偿(参考芯片资料)。

五、PCB 布局与热设计

  • 将输入电容紧邻 VIN 引脚,开关节点(SW)走线尽量短、宽并远离敏感模拟信号;
  • 将电感与输出电容靠近 SW 与 VOUT 布局,减小环路面积以降低 EMI;
  • SOT-23-5 无大面积散热垫,建议在封装下方与周边布置铜箔并与地层对接以增强散热;高载条件下注意温升。

六、保护与注意事项

  • 工作温度与输入极限需满足规格,过温或过载时按数据手册建议处理;
  • 在电池供电场景下关注低电压启动与掉电行为,必要时在系统加入外部上电检测或使能控制;
  • 出于可靠性考量,推荐在设计验证阶段进行效率、热场与 EMI 测试。

七、封装与订购

  • 型号:ME2107A50M5G;品牌:MICRONE(南京微盟);封装:SOT-23-5。
  • 详细引脚定义、电气特性曲线与典型应用电路请参照官方数据手册,以确保设计正确性与符合认证要求。

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
