ME2188A33PG 产品概述

一、产品简介

ME2188A33PG 是南京微盟(MICRONE)推出的一款升压型 DC-DC 转换器,封装为 SOT-89,专为低电压电源到 3.3V 稳定供电而设计。芯片集成开关管并采用同步整流结构,工作输入电压范围宽(0.9V~5V),在 320kHz 开关频率下可稳定输出固定 3.3V,最大持续输出电流可达 300mA。器件静态电流仅 7.5µA,工作温度范围为 -40℃~+125℃,适合电池供电和低功耗场景。

二、主要特性

  • 功能类型:升压型(Boost)单路固定输出 3.3V
  • 输入电压:0.9V ~ 5V,支持极低起始电压应用
  • 输出电流:最高 300mA(持续)
  • 开关频率:320kHz,有利于电感和滤波器的小型化
  • 同步整流:内置同步整流以降低整流损耗、提高效率
  • 静态电流:Iq = 7.5µA,适合电池待机低功耗要求
  • 开关管:内置,简化外部元件与 PCB 布局
  • 封装:SOT-89,体积小,利于空间受限的应用
  • 工作温度:-40℃~+125℃,适合工业级环境

三、典型应用

  • 单节或低电压电池供电的便携设备(传感器节点、遥控器、便携式仪表)
  • 物联网(IoT)终端、无线模块(蓝牙、Zigbee 等)电源升压
  • 便携通信与数据采集设备,需要从低电压电池提升到 3.3V 的场景
  • 能量采集或近耗尽电池仍需稳定 3.3V 输出的系统

四、设计要点与布局注意事项

  • 外围器件:建议配合低直流电阻(低 Rdc)功率电感和低 ESR 的输入/输出电容,降低纹波并保证瞬态响应。
  • 电感与电容选型应根据最大输出电流和芯片峰值电流选择合适电流额定值与容值。
  • PCB 布局:输入电容应尽可能靠近芯片电源引脚放置,开关节点走线尽量短且宽,输出回路形成良好接地平面以降低 EMI。
  • 散热:SOT-89 包装受限于散热能力,对持续大电流工作或高环境温度场合,应在 PCB 放大铜箔面积并考虑热过载保护设计。
  • 启动与稳态:芯片支持从低至 0.9V 的启动,但在极低输入电压下输出能力受限,建议在系统设计阶段验证启动电压下的负载能力。

五、封装与可靠性

SOT-89 封装体积小、焊接方便,适合体积受限的便携类产品。器件工作温度覆盖工业级范围(-40℃~+125℃),满足大多数工业与消费电子应用的可靠性要求。同步整流与低静态电流设计有助于延长电池寿命并提高系统效率。

六、选型建议

若设计要求从 0.9V~5V 输入稳定生成 3.3V、并且需要中等电流(≤300mA)且对功耗敏感,ME2188A33PG 是紧凑、成本效益较高的选择。对更高电流或更严格热管理要求的场合,建议评估封装散热能力或采用更大封装的替代器件。

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
