BL8531CC3TR40 产品概述
一、产品简介
BL8531CC3TR40 是贝岭（BELLING）推出的一款升压型 DC-DC 开关稳压器，封装为 SOT-89-3。器件内置开关晶体管，拓扑为升压（Boost），工作电压范围宽（0.8V ~ 4V），输出固定 4.0V，输出电流可达 200mA，静态电流仅 4μA，开关频率典型值为 400kHz。工作环境温度范围为 -40℃ ~ +85℃（TA）。
二、主要特点
- 工作电压范围：0.8V ~ 4.0V，适合单节电池或低电压能量输入场景；
- 内置开关管，节省外部MOSFET元件，简化电路设计；
- 低静态电流（Iq ≈ 4μA），适合电池供电与低功耗应用；
- 可输出最大 200mA 的负载电流，满足多数便携式设备需求；
- 开关频率约 400kHz，有利于减小外部电感与滤波元件体积；
- 封装 SOT-89-3，体积小，适合空间受限设计。
三、典型应用
- 便携式电子产品（手持仪表、小型玩具）；
- 传感节点、低功耗物联网设备和无线传输模块；
- 纽扣/碱性/锂离子电池升压到固定供电轨；
- 低电压能量采集系统与备用电源管理。
四、设计与选型建议
- 外围器件：需配合低直流电阻（低RDC）电感、肖特基整流二极管（如外置）、低ESR 输入/输出电容以降低损耗与纹波；
- 电感与电容的选择应依据最大输出电流、允许纹波及开关频率进行计算；400kHz 允许使用较小电感以节省空间；
- 布局要点：输入端与开关节点走线短、地线集中回流，输出电容靠近器件放置以减少寄生；SOT-89-3 封装散热能力有限，负载大时注意环境温升与热阻；
- 保护与可靠性：为提升抗瞬态能力，可在输入端加 TVS 或滤波网络；高温或大电流工况下建议降额使用并做热设计验证。
五、封装与订购
- 封装：SOT-89-3，适合自动贴片生产；
- 品牌：BELLING（贝岭）；型号：BL8531CC3TR40。订购时注意完整型号与卷带/散装形式，以保证生产一致性。
总结：BL8531CC3TR40 以其低静态电流、内置开关和宽输入范围，适合对能耗敏感且需要把低电压升至 4V 的便携与物联网类应用。设计时注意外围被动元件选型与 PCB 布局及散热评估，可获得稳定可靠的输出性能。

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.
