TEA1721AT/N1,118是恩智浦(NXP)推出的一款非隔离离线反激式转换器,专为中小功率(通常10W以内)AC-DC电源应用设计,采用SOIC-7紧凑型封装,集成多维度保护功能与原边反馈(PSR)技术,在简化外围电路的同时兼顾可靠性与效率,适配消费电子、工业辅助电源等场景的紧凑化需求。
该器件属于离线电源控制器范畴,针对高压交流转直流(AC-DC) 场景优化,无需次级反馈绕组即可实现输出电压/电流控制,适合对成本、体积敏感的领域。其非隔离拓扑设计进一步降低了电路复杂度,尤其适配小功率低电压输出的应用(如手机充电器、智能设备电源)。
该器件内置4类核心保护功能,大幅提升系统可靠性:
作为恩智浦的成熟产品,TEA1721AT/N1,118通过了严格的可靠性测试,符合RoHS环保标准,可长期稳定运行于恶劣环境。其集成度高、外围简单的特点,也便于工程师快速完成电源方案设计与调试。

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.
