MSMP2307DN-LF-Z是美森科(MSKSEMI)推出的一款高性能降压型同步整流DC-DC转换器,针对小体积、高效率、宽适应场景的电源设计需求优化,广泛适用于消费电子、工业控制及便携式设备等领域。
美森科(MSKSEMI)作为专注电源管理芯片研发的厂商,聚焦高可靠性、高集成度的功率转换方案。MSMP2307DN-LF-Z定位于中小功率宽输入降压应用,通过内置同步整流、高频开关等设计,平衡了性能与成本,适合批量生产的紧凑式电源需求。
该芯片的核心参数直接支撑其应用灵活性,具体表现为:
支持4V~18V输入电压,覆盖单节锂电池(3.7V满电4.2V)、双节锂电池(7.4V)、12V适配器、9V快充等常见输入源,无需额外适配电路即可兼容多种供电场景。
采用内置同步整流MOS管替代传统续流二极管,导通压降更低(典型值<0.1V),显著提升转换效率——在中等负载(如1A输出)下效率可达92%以上,减少电源发热,无需额外散热器件。
500kHz的固定开关频率高于传统200kHz方案,可选用更小容值的电感(如10μH)和输出电容(如100μF陶瓷电容),大幅缩小PCB布局面积,适配便携式设备的紧凑空间需求。
无需外置N-MOSFET和续流管,简化BOM(物料清单),降低设计复杂度与成本;同时减少外部元件的布局干扰,提升电路稳定性。
通过外部两个分压电阻可灵活设置输出电压(参考电压典型值0.8V),覆盖1V~15V常见负载电压,适配MCU、FPGA、传感器等不同器件的供电需求。
支持-40℃~+85℃工业级温度范围,可适应户外低温环境(如北方物联网节点)、设备内部高温区域(如机顶盒散热腔),满足 harsh 场景的可靠性要求。
采用ESOP-8贴片封装,尺寸小巧(约5.0mm×6.0mm),引脚间距合理,易焊接且适合高密度PCB布局,可直接集成于小型电源模块或设备主板。
该芯片的核心价值在于平衡性能与成本:内置同步整流+开关管减少BOM数量,500kHz高频缩小体积,宽温宽压提升场景适配性,适合中低端到中端电源设计的批量需求。相比同类型异步整流芯片,效率提升5%~8%;相比外置开关管方案,BOM成本降低约15%,布局空间节省20%以上。
总结:MSMP2307DN-LF-Z是一款高性价比的降压型同步整流DC-DC转换器,凭借宽输入、高效率、小体积与工业级温度范围,成为消费电子、工业控制等领域中小功率电源设计的优选方案。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
