TNY284DG-TL是Power Integrations(帕沃英蒂格盛)推出的中小功率离线反激式转换器,专为非隔离/低隔离需求的电源设计,采用副边反馈控制架构,集成度高,可简化外部电路布局。
其核心拓扑为反激式,通过变压器磁耦合实现能量传输(非隔离应用可省略额外隔离绕组),开关频率稳定在132kHz(典型值),覆盖124kHz~140kHz范围——处于人耳不可闻频段,既避免电磁干扰(EMI)问题,又能通过高频优化变压器体积,平衡效率与成本。
TNY284DG-TL内置多重保护机制,无需外部额外元件,提升系统可靠性:
基于拓扑与参数特性,该芯片适用于以下场景:
TNY284DG-TL以宽电压适应、多重保护、紧凑封装为核心优势,适合中小功率电源设计需求,是消费电子、工业控制等领域的实用选择,可有效降低电源模块的设计复杂度与成本。

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.
