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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
