TEA1761T/N2/DG,118 产品概述

一、概述

TEA1761T/N2/DG,118 是恩智浦(NXP)面向隔离式反激(flyback)AC-DC/隔离稳压应用的高可靠性控制器。器件工作电压范围宽(8.6V~38V),支持准谐振(QR)与不连续导通(DCM)两种工作模式,采用SO-8 封装,额定工作温度范围极宽(-20℃~+150℃),适合严苛环境和工业级应用。

二、主要功能与特性

  • 隔离结构,适用于副边反馈的反激拓扑;
  • 恒流(CC)与恒压(CV)双模控制,便于用于充电器及LED驱动等需要电流/电压闭环的场景;
  • 过热保护(OTP)和欠压保护(UVP),提升系统可靠性;
  • 工作模式支持QR与DCM,可在轻载与满载下兼顾效率与电磁兼容(EMI);
  • 最大耗散功率(Pd)约450mW,设计时需注意热量管理与散热布局。

三、反馈与控制

器件采用副边反馈方式,常与光耦或副边参考/二次侧基准电路配合,实现精确的恒压/恒流闭环。副边反馈可以减小主回路误差并提高稳压精度,但需注意反馈回路的带宽与补偿设计,以确保系统稳定性并避免冲击电流。

四、设计要点与建议

  • 输入电压与元件选型:确保外围元件(尤其是开关管、整流与滤波器)满足8.6V~38V 的工作范围与峰值应力;
  • 热管理:Pd=450mW 意味着在高环境温度下需通过优化PCB散热路径或加装散热片来控制结温,保证OTP在可控范围内;
  • EMI与抑制:QR模式有利于降低开关损耗与EMI,仍建议加入合适的吸收网络、斜坡补偿与磁芯选型以满足传导/辐射规范;
  • 保护电路:结合器件内置OTP/UVP,外部可增加过流、短路及输出过压保护以增强系统安全性。

五、典型应用

  • 小功率隔离式适配器与充电器;
  • LED恒流驱动与照明电源;
  • 工业控制电源与通信设备的次级供电;
  • 对温度与可靠性要求高的嵌入式电源解决方案。

六、封装与可靠性

SO-8 封装便于自动化贴片生产与系统集成。器件宽温规范(-20℃~+150℃)和内建保护功能,使其适用于汽车电子、工业控制等需要长期稳定运行的应用场景。设计时请参考恩智浦提供的详尽数据手册与典型应用电路,按照推荐的PCB布局与外围器件取值进行实现,以确保最佳性能与可靠性。

如需进一步的电路建议、参考设计或与具体应用匹配的外围元件选型,可以提供系统功率、输入类型与目标输出规格以便给出更详细的设计指导。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Replenishment inquiry Typical RFQ workflow
