TC7660SEOA713 是 MICROCHIP(美国微芯)系列的一款小功率反相 DC‑DC 电源芯片,采用 SOIC‑8 封装。器件将正电源电压反相输出,可在 1.5V ~ 12V 输入范围内生成对应的负电压(典型输出范围 -1.5V ~ -12V),额定输出电流约 20mA,适合为低功耗模拟电路和传感器等提供负电源轨。
该器件采用电荷泵结构,内部开关通过自适应频率控制在不同负载下优化效率与噪声。静态电流低(≈160μA),适合电池供电或低静态功耗场合。输出阻抗约 60Ω,意味着在接近额定电流时会有明显压降。因此本器件适合驱动小电流负载或作为参考/偏置电源。器件支持级联(cascade),可用于生成更高幅度的负电压或构建多级电源网络,但级联时需注意总电流与器件应力。
TC7660SEOA713 是一款面向小电流、低功耗应用的反相电荷泵 IC,具有输入电压范围宽、自适应开关频率与较高转换效率等优点。对于需要在单电源系统中生成负电压以驱动模拟前端或实现偏置的场合,该器件提供了体积小、封装成熟(SOIC‑8)且使用方便的解决方案。使用时应关注负载限制、去耦与布线,以获得最佳性能与可靠性。

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.
