ME2188A28M3G 产品概述

一、概述

ME2188A28M3G 是南京微盟(MICRONE)推出的一款升压型 DC-DC 转换器,采用 SOT-23 小封装设计,适用于空间受限且强调超低静态电流的电池供电系统。芯片内部集成开关管并采用同步整流架构,在输入电压 0.9V 至 5V 范围内稳压输出固定 2.8V,最大输出电流可达 300mA,开关频率为 320kHz,工作温度范围 -40℃ 至 +125℃。

二、主要特性

  • 升压拓扑,固定输出 2.8V,单通道输出设计,便于系统集成。
  • 输入电压宽范围:0.9V ~ 5V,可从接近耗尽的单节电池或低压能量源启动。
  • 输出电流高达 300mA,满足中等功率负载需求。
  • 同步整流结构,降低整流损耗,提高转换效率及续航能力。
  • 内置开关管,减少外部器件数量与占板面积。
  • 开关频率 320kHz,兼顾元件尺寸与效率,可使用较小体积的电感器件。
  • 静态电流仅 7µA,适合长期待机与低功耗应用。
  • 宽温工作可靠,适应工业级环境(-40℃~+125℃)。

三、典型应用

  • 便携式手持设备、低功耗消费类电子。
  • 物联网节点、无线传感器、遥测模块等电池供电的智能终端。
  • 低压电池驱动的照明指示或驱动电路(需匹配功率要求)。
  • 紧凑型电子仪器、备电回路与能量采集系统的升压电源方案。

四、设计与布局建议

  • 外围元件:尽管芯片内置开关管,仍需配合适当电感与输入/输出低 ESR 电容以保证稳定性与低纹波。根据功率与占板面积选取 μH 级低 DCR 电感。
  • 布局要点:输入输出电容尽量靠近芯片电源脚与地端放置,缩短高电流回路走线;将感性元件与高频走线隔离,以减少电磁干扰。
  • 热管理:SOT-23 封装需关注散热路径,长时间高负载工作时注意 PCB 铜箔散热和器件温度。
  • 启动与稳定性:在极低输入电压启动或快速负载突变时,选择合适的补偿及滤波元件,以保证瞬态响应。

五、封装与可靠性

ME2188A28M3G 提供 SOT-23 封装,适用于自动贴片生产与小型化设计。器件符合工业级温度规范,适配多种严苛工作环境,便于在消费、工业与 IoT 场景中长期可靠运行。

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
