IW673-20是瑞萨电子针对中小功率反激式电源开发的数字绿模同步整流控制器,核心定位为低功耗、高效率、恒流输出的电源控制方案,广泛适配LED驱动、小型适配器等场景。
该控制器集成数字控制架构与绿模(Green-Mode)节能技术,结合同步整流设计,解决传统肖特基整流器效率低、待机功耗高的问题,同时支持恒流(CC)模式与断续导通模式(DCM),满足反激拓扑下的稳定输出需求:
IW673-20的核心参数适配其应用场景,关键指标如下:
注:其他扩展参数(如待机功耗、输出电流精度、工作温度范围等)需参考瑞萨官方 datasheet,但核心参数已覆盖用户需求。
IW673-20的设计特性使其适配以下主流场景:
IW673-20采用SOT-23-6贴片封装,尺寸紧凑(典型尺寸:2.9×1.6×1.0mm),适合高密度电路设计。引脚功能包含核心控制与驱动:
IW673-20在同类产品中具备以下突出优势:
以上为IW673-20的核心产品概述,具体设计需结合瑞萨官方 datasheet 与应用场景进行电路优化。

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.
