TNY264PN AC-DC控制器产品概述

一、产品定位与核心属性

TNY264PN是Power Integrations(帕沃英蒂格盛)推出的隔离式AC-DC集成控制器,专为中小功率(5-15W)反激式电源设计。该器件将高压功率MOSFET与控制电路深度集成,以高可靠性、宽工作范围和多重保护功能为核心,替代传统分立方案,广泛应用于消费电子、工业控制及照明领域。

二、关键电气参数解析

TNY264PN的核心参数匹配中小功率隔离电源的典型需求,关键特性如下:

  1. 隔离设计:输入输出完全电气隔离,满足UL、CE等安全规范,避免高压干扰低压电路;
  2. 开关频率:固定132kHz,既规避100kHz以下的音频噪声,又无需高频元件(如200kHz以上),平衡体积与成本;
  3. 最大占空比:65%,结合反激拓扑能量传输特性,在85VAC~265VAC宽输入范围内稳定输出;
  4. 晶体管耐压:内置700V高压MOSFET,可承受220VAC整流峰值(约310V)、电网波动(265VAC下375V峰值)及开关尖峰,安全裕量充足;
  5. 工作温度:结温范围-40℃~+150℃,适应低温(北方户外)、高温(密闭小家电)等恶劣环境;
  6. 反馈方式:副边反馈(通过副边绕组/光耦调节),输出电压精度远高于原边反馈,适合对稳定性要求高的场景(如充电器);
  7. 封装:PDIP-8-B(8脚直插),便于手工焊接与批量生产,引脚布局简洁,降低PCB设计难度。

三、集成多重保护功能

TNY264PN无需外部元件即可实现4类核心保护,提升设备可靠性:

  1. 过热保护(OTP):结温超150℃时自动关断,温度下降至安全范围后自动重启,防止器件烧毁;
  2. 短路保护(SCP):输出短路时限制原边电流至安全值,避免变压器饱和或MOSFET损坏,短路排除后自动恢复;
  3. 欠压保护(UVP):输入电压低于85VAC时不启动,防止低电压下输出不稳定;
  4. 过流保护(OCP):检测原边电流超阈值时,进入自动重启模式(关断→短暂延迟→重启),避免过载失效。

四、拓扑结构与工作优势

采用反激式拓扑,是中小功率隔离电源的主流选择,核心优势:

  • 隔离安全:输入输出完全隔离,满足家电、工业安全规范;
  • 宽输入兼容:支持全球通用市电(85VAC~265VAC),无需额外适配;
  • 高集成度:内置700V MOSFET,减少分立元件,降低BOM成本;
  • 效率平衡:132kHz频率下实现70%~85%转换效率,满足多数应用需求。

五、典型应用场景

基于特性,TNY264PN适用于以下场景:

  1. 便携设备充电器:手机、平板等5-10W充电器,副边反馈保证输出精度,隔离设计符合安全标准;
  2. LED驱动电源:小功率LED灯泡、台灯、应急灯驱动,宽温范围适应不同环境;
  3. 小家电控制电源:电饭煲、电水壶、加湿器控制板辅助供电,集成保护提升设备寿命;
  4. 工业辅助电源:PLC、传感器、小型仪表低功率供电,-40℃~+150℃结温适应工业现场。

六、品牌与可靠性验证

Power Integrations是全球AC-DC电源芯片龙头,TNY系列经多年市场验证:

  • 高可靠性:严格生产工艺与测试,故障率低于行业平均;
  • 兼容性强:适配多种反激变压器,外部元件选型灵活;
  • 合规性:符合UL、CE、RoHS等标准,降低产品认证难度。

TNY264PN以高集成度、宽适应性和多重保护,成为中小功率隔离电源的优选方案,覆盖消费电子到工业领域的多样化需求。

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
