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。
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。
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。

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.
