IW1760B-00 离线反激转换器产品概述
IW1760B-00是瑞萨电子（RENESAS）推出的一款隔离式离线反激转换器，针对中小功率（最大20W）AC-DC电源应用优化，采用原边反馈设计简化电路，集成多重保护机制提升可靠性，适合消费电子、家电及工业辅助电源等场景。
一、核心应用场景
该器件定位为中小功率隔离电源解决方案，典型应用包括：
- 消费电子：手机充电器、机顶盒电源、路由器电源；
- 家电领域：智能家电控制板电源、小型厨房电器电源；
- 工业辅助：PLC（可编程逻辑控制器）辅助电源、传感器供电模块。 其隔离特性满足安全认证要求，原边反馈设计降低BOM成本，适配成本敏感型产品。
二、关键性能参数
- 功率与拓扑：最大耗散功率20W，采用反激式拓扑（单端隔离设计，结构紧凑）；
- 开关频率：典型开关频率79kHz，平衡EMI（电磁干扰）与变压器设计复杂度；
- 反馈方式：原边反馈（无副边光耦），简化电路布局，减少元件数量；
- 封装：SOIC-8贴片封装，体积小（5.3×6.0mm），适合PCB紧凑设计。
三、多模式工作设计
IW1760B-00支持三种工作模式切换，覆盖全负载范围优化效率：
- 准谐振（QR）模式：轻载时（如待机状态）降低开关损耗，提升能效；
- PFM调制：更轻载场景下进一步减少功耗，适配低功耗需求；
- PWM调制：满载时保持输出电压稳定，确保负载供电精度。 多模式设计使电源在10%~100%负载范围内均有良好能效表现，符合主流能效标准（如六级能效要求）。
四、多重保护机制
集成四大核心保护功能，保障电源与负载安全：
- 过热保护（OTP）：芯片结温超过阈值时自动关断，温度回落至安全范围后重启；
- 短路保护（SCP）：输出短路时限制电流输出，避免持续大电流损坏器件；
- 过压保护（OVP）：输出电压异常升高时关断，防止损坏敏感负载；
- 过流保护（OCP）：输出电流超过额定值时限制功率，避免过载烧毁。 保护机制无需额外外围元件，简化设计同时提升可靠性。
五、易用性与可靠性
- 电路简化：原边反馈无需副边光耦、稳压管等元件，BOM成本降低约15%（对比副边反馈方案）；
- 封装适配：SOIC-8贴片封装支持自动化焊接，适合大规模生产；
- 品牌背书：瑞萨电子的半导体产品经过严格可靠性测试（如高温老化、EMC测试），长期供应稳定，适配工业级与消费级场景。
六、总结
IW1760B-00以高集成度、低成本、高可靠性为核心优势，适合中小功率隔离AC-DC电源设计。其原边反馈设计简化电路，多模式工作提升能效，多重保护保障安全，是消费电子、家电及工业辅助电源的优选方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
