MD7660 是明达微推出的一款高效能、低功耗的电荷泵反相/倍压转换芯片,采用 SOP-8 封装,针对空间受限且对负电源或高压微功率源需求的便携式与嵌入式系统而设计。器件支持 3V~12V 的工作电压范围,最高可耐受 12V 电压,工作温度覆盖 -40℃ 到 +85℃,在低静态电流与高能量效率之间取得良好平衡。
MD7660 可在反相(产生负电压)与倍压(产生更高正电压)两种拓扑间切换,用户可根据系统需求通过外部引脚配置或控制信号选择工作模式。器件内置自适应开关频率机制,可根据负载与输入条件动态调整开关频率,降低开关损耗与电磁干扰,同时在轻载时保持极低静态电流,从而延长电池寿命。
SOP-8 封装利于标准 PCB 装配及生产测试。器件工作温度范围 -40℃ 至 +85℃,适应工业级环境。为保证长期可靠性,建议:
总结:MD7660 以其低静态电流、高效率与灵活的拓扑切换特性,适合对功耗、体积和成本敏感的便携与嵌入式系统,为负电源或高压小功率源提供稳定可靠的解决方案。对于需详细典型电路与参数曲线的设计,可参考明达微的详细数据手册以获得更精确的设计数据。

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.
