TC7660SEOA713 产品概述

一、产品简介

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。

二、主要规格

  • 功能类型:反相(电荷泵式 DC‑DC 逆变器)
  • 工作电压:1.5V ~ 12V
  • 输出电压范围:约 -1.5V ~ -12V(随输入电压变化)
  • 最大输出电流:固定 20mA(典型 / 额定)
  • 静态电流 (Iq):约 160μA
  • 输出等效电阻:约 60Ω
  • 峰值能量效率:可达 98%(典型工作点)
  • 开关频率:约 45kHz(自适应开关频率)
  • 工作温度:0℃ ~ +70℃
  • 封装:SOIC‑8
  • 功能特性:自适应开关频率、级联支持

三、功能与特性说明

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。

四、典型应用场景

  • 低功耗放大器或运算放大器的负电源偏置
  • 传感器和数据采集前端的负偏置电源
  • 液晶驱动/像素偏压(小电流场合)
  • 便携式仪器与电池供电系统的负轨生成
  • 需要小电流反相电源的模拟参考与偏置电路

五、实用建议与注意事项

  • 输入电压应严格在 1.5V~12V 范围内;超出范围可能导致器件异常或损坏。
  • 为降低纹波与提升稳定性,建议在芯片的电荷泵电容与输出端使用低 ESR 电容,并尽量缩短连接导线/走线长度。
  • 负载应控制在器件额定输出电流(约 20mA)以内,负载过大将导致输出电压下压并增加发热。
  • 级联使用时,需评估每级的电流消耗与累积压降,必要时增加限流或滤波元件以保护器件并保证稳定性。
  • 工作环境温度限定为 0℃~+70℃,高温工况下应注意散热与可靠性。
  • PCB 布局上应注意开关节点的回流路径,减小环路面积以抑制 EMI。

六、总结

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。

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.
