IW636-07是瑞萨电子(RENESAS)推出的AC/DC次级侧控制器,专为支持Qualcomm Quick Charge 3.0(QC3.0)协议的USB接口电源设计,核心定位是实现高效、稳定的快充电源管理,广泛应用于各类消费电子快充设备。
IW636-07突破传统电源设计思路,采用次级侧控制架构,无需光耦反馈元件即可实现精准电压/电流调节,是QC3.0快充方案的关键组件。其核心价值体现在:
支持3V~16V直流输入电压,覆盖手机充电器、移动电源等设备的典型工作范围,适应不同电源拓扑的次级侧供电需求,无需额外电压转换电路。
无需光耦或TL431等反馈元件,通过内部算法实现输出电压/电流的精准调节,减少外部元件数量,提升电路可靠性与抗干扰能力。
严格遵循Qualcomm Quick Charge 3.0技术规范,支持动态电压调节(DVS),可根据负载设备需求自动切换电压档位(5V/9V/12V),提升充电速度的同时保护电池安全。
采用SOT-23-6封装,尺寸紧凑(2.9mm×2.5mm×1.0mm),适合小型化快充产品(如超薄充电器、便携移动电源),有效节省PCB布局空间,助力产品轻薄化设计。
次级侧控制架构减少了反馈环路的外部元件,无需复杂的光耦隔离电路,降低设计难度与生产复杂度,缩短产品开发周期30%以上(对比传统光耦方案)。
优化的控制算法使电源转换效率可达92%以上(典型工况),减少发热,延长设备使用寿命,同时降低能耗,符合绿色环保要求。
支持多种AC/DC拓扑(如反激式、降压式),可与瑞萨其他电源管理芯片(如初级侧控制器ISL95830)配合,构建完整的快充解决方案,覆盖从10W到45W的快充功率范围。
IW636-07主要应用于支持QC3.0协议的消费电子设备电源,包括:
总结:IW636-07作为瑞萨针对QC3.0快充的专用次级控制器,凭借宽电压范围、简化电路、高可靠性等优势,成为消费电子快充方案的优选组件,助力产品实现高效、稳定的快充功能,同时降低设计与制造成本。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
