BL8531CB5TR36 产品概述

一、概述

BL8531CB5TR36 是贝岭(BELLING)推出的一款升压型 DC-DC 转换器,封装为 SOT-23-5。器件采用内置开关管的升压拓扑,为单路固定输出 3.6V 提供稳健的电源解决方案,适用于低电压电源提升场合,如单节电池或低压供电的便携/物联网设备。

二、主要规格

  • 功能类型:升压型(Boost)
  • 输入电压范围:0.8V ~ 3.6V
  • 输出电压:固定 3.6V
  • 输出电流:最大 200mA
  • 开关频率:350kHz
  • 静态电流(Iq):约 4μA(空载低功耗)
  • 同步整流:否(外部采用肖特基二极管)
  • 开关管:内置
  • 通道数:1
  • 工作温度范围:-40℃ ~ +85℃(TA)
  • 封装:SOT-23-5
  • 型号:BL8531CB5TR36

三、特点与优势

  • 宽输入电压范围:可从低至 0.8V 的电源启动,适合单节锂电/碱性/镍氢电池等场景。
  • 低静态电流:4μA 的待机电流有利于延长电池寿命,适合长期待机的传感器和可穿戴设备。
  • 内置开关管:简化外部布局与器件选型,减少整体体积。
  • 固定输出与可预测性:3.6V 固定输出方便为上游/下游电路提供稳定参考,不需外部反馈网络。
  • 中等开关频率(350kHz):在效率与电感体积之间取得平衡,有利于使用小体积电感和滤波器。

四、典型应用

  • 可穿戴设备、智能手环
  • 物联网节点、无线传感器
  • 便携式电子产品(单节电池供电)
  • 低功耗测量仪器与控制模块

五、外部器件与布局建议

  • 由于为非同步设计,输出端需选用低正向压降的肖特基二极管以降低整流损耗。
  • 选用适当值的电感(根据负载和效率要求,通常选择低直流电阻的封装化电感),并确保电感电流评级高于峰值电流。
  • 输入/输出旁路电容应放置于芯片引脚附近,尽量使用低 ESR 的陶瓷电容以降低噪声与纹波。
  • 布局要点:开关节点(SW)、二极管、输出电容和电感连线要尽量短且粗;将地回路集中,减小回路面积;器件间保持合理间距以利散热。
  • SOT-23-5 封装散热能力有限,若工作在高负载或高环境温度下,应在 PCB 上提供足够的铜箔散热区域。

六、选型与封装信息

  • 品牌:BELLING(贝岭)
  • 型号:BL8531CB5TR36
  • 封装形式:SOT-23-5(适合空间受限的便携产品)
  • 订购型号示例:BL8531CB5TR36(请根据供应商提供的卷带/单件信息确认包装与最小订购量)

七、设计注意事项与建议

  • 在高负载短路或过温情况下,参考厂商资料页确认保护机制与热关断特性。
  • 在实际应用中建议做负载与效率测试,选择匹配的二极管、电感与滤波电容,平衡效率、纹波和器件尺寸。
  • 若需更高效率或更大输出电流,可考虑同步型升压器或外部 MOSFET 方案,但会增加复杂度与器件数量。

如需原理图示例、参考布局或更详细的电气特性曲线,请提供您的典型输入/负载条件,我可进一步给出针对性的元件选型与 PCB 布局建议。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
