CN5611 产品概述
一、产品简介
CN5611 是由 CONSONANCE（上海如韵）推出的一款单通道恒流 LED 驱动芯片，工作电压范围为 DC 2.7V ~ 6V，输出恒流 800mA。芯片内置开关管，采用 SOT-89-5 封装，面向高亮单串或小功率模块的稳流驱动需求，兼顾效率与体积，适配手电、车灯、通用照明等空间受限的应用。
二、主要特点
- 单通道恒流输出：800mA 恒流驱动，适合高亮 LED。
- 工作电压：DC 2.7V ~ 6V，适配常见电源与电池组。
- 调光方式：支持 PWM 调光接口，便于亮度调节和场景控制。
- 内置开关管：器件集成开关，简化外部器件需求与 PCB 设计。
- 保护功能：内建过温保护（OTP）和短路保护（SCP），提高系统可靠性。
- 恒流精度：±8%（典型/最大视具体工况），保证光通稳定一致。
- 工作温度：-40°C ~ +85°C，适应宽温度环境。
三、电气参数要点
- 输入电压：2.7V ~ 6V DC
- 输出电流：800mA（恒流）
- 恒流精度：8%
- 调光：PWM（建议输入高电平/低电平驱动）
- 封装：SOT-89-5
四、应用场景
- 手持照明（手电筒、探照灯）
- 汽车小功率照明（示宽灯、示廓灯等，需符合车规外围设计）
- 通用背光与指示灯
- 小型泛光、建筑装饰照明模块
五、封装与热管理
SOT-89-5 小型封装适合空间受限的设计，但在高电流工作下仍需关注散热。建议：
- 在 PCB 下方及周边使用充足的铜箔铺铜，增大散热面积。
- 关键焊盘做热过孔或加大热填充，降低结温。
- 在高环境温度或连续满载工况下考虑功率退让或热保护策略。
六、典型应用电路与使用注意事项
- 按参考电路连接输入滤波电容和输出元件，保证稳定性与低纹波。
- PWM 调光端建议使用随芯片说明书推荐的频率和占空比范围，以免影响恒流精度或引入可听噪声。
- 短路或过载工况会触发 SCP/OTP，设计时应留有恢复与报警机制。
七、可靠性与保护机制
CN5611 集成 OTP 与 SCP，提高系统抗故障能力。器件在异常条件下能自动限流或进入保护关断状态，保护 LED 与电源系统。建议在系统级增加熔断或限流保险元件，以应对极端故障。

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.
