B1505S-1WR3 产品概述

一、产品简介

B1505S-1WR3 是 YLPTEC(易川)推出的一款小体积、高效率的微功率隔离式 DC/DC 模块。模块为定电压输入、隔离非稳压的单路输出设计,额定输出功率 1W,适合在板上电源系统中生成与主电源隔离的低功率电压源。模块体积小(11.5 × 6 × 10 mm,SIP 封装),方便在空间受限的场合进行并排布置或嵌入式系统应用。

二、主要规格参数

  • 输入电压(Vin):15V(定电压输入,建议输入波动范围 ±10%)
  • 输出电压(Vout):5V(单路输出)
  • 输出功率:1W
  • 输出电流(最大):200mA
  • 转换效率:约 88%
  • 隔离电压(Vrms):1.5 kV(1500V)
  • 最大容性负载:2400 μF
  • 开关频率:100 kHz
  • 纹波噪声:30 mVp-p(典型)
  • 保护功能:短路保护、自动故障恢复、过热保护
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装及尺寸:SIP,11.5 mm × 6 mm × 10 mm
  • 输出通道数:1(单路)

三、核心特性

  1. 小体积:SIP 小封装适合高密度板上布局,节省空间。
  2. 高效率:典型效率 88%,降低系统热耗并提高可靠性。
  3. 隔离性能:1500Vrms 隔离等级,满足常见隔离需求,适用于信号隔离与地环路隔离场合。
  4. 容性驱动能力强:支持最大 2400 μF 的输出容性负载,便于驱动瞬态负载或配合大电容滤波。
  5. 保护完善:短路与过热保护,并具备自动故障恢复功能,提高系统安全性与维护便利性。
  6. 低噪声:30 mVp-p 的典型纹波适用于多数数字电路及一般低频模拟电路需求。

四、典型应用场合

  • 需要与主电源隔离的板上电源:通信接口、隔离信号处理电路。
  • 纯数字电路电源:MCU、逻辑电平隔离与小功率外设供电。
  • 继电器驱动电路:供给继电器及相关驱动电路(注意继电器启动电流峰值)。
  • 数据交换与接口电路:用于需要隔离的接口模块(如 RS-485、隔离型串行接口等)。
  • 一般低频模拟电路(对输出稳定度要求不高的场合)。

五、使用与选型建议

  • 输入条件:本模块为定电压输入设计,适合输入电压在 15V ±10% 范围内稳定的场合。若输入电压波动较大或需宽输入范围,应考虑带宽输入规格的器件或在输入端加稳压措施。
  • 输出精度:模块为隔离非稳压类型,输出稳压能力有限;对输出精度要求严格的场合建议在模块输出端加稳压芯片或 LDO 做二次稳压。
  • 滤波与旁路:尽管模块内部带有滤波,建议在输入端和输出端各并联合适的旁路电容(尤其在高频纹波抑制上,加入 0.1 μF 陶瓷电容与 10 μF 电解/固态电容组合效果更佳),并将旁路电容尽量靠近模块引脚布置。
  • 容性负载:最大支持 2400 μF,但在应用中请注意负载启动时的瞬态冲击及模块保护机制;若输出后接大电容,建议评估启动电流与稳定时间。
  • 散热与环境:尽管转换效率较高,长期满载运行会产生热量。请注意 PCB 散热设计(保持周边铜箔、避免密封小腔)并遵守工作温度范围 -40℃ 至 +85℃。在高温环境下建议适当降额使用。
  • EMC 与地线布线:用于敏感模拟或高精度电路时,建议在模块输入输出处做好共模干扰抑制(配合共模电感或差模滤波),并合理划分接地回路以减少地环路噪声。

六、封装与安装

模块采用 SIP 封装,尺寸 11.5 × 6 × 10 mm,非常适合插装或波峰/手工焊接在 PCB 上。建议在设计 PCB 时为模块留出足够的焊盘面积和周边过孔,以利于散热和机械固定。布线时输入输出走向分开,避免高频回流与敏感信号线近距平行。

七、可靠性与保护说明

B1505S-1WR3 具备短路保护和过热保护,并支持自动故障恢复,能够在异常解除后自动恢复工作状态,减少人工干预。隔离电压 1.5 kV 可满足多数工业与通信设备的隔离要求。推荐在系统设计中配合合适的输入保险丝与浪涌保护元件,以进一步提高整机可靠性。

总结:B1505S-1WR3 是一款体积小、效率高、隔离性能可靠的微功率 DC/DC 模块,适合用于对隔离、体积和功耗有严格要求但对输出稳压精度要求不高的板上电源场合。根据具体应用场景,可通过外部滤波与二次稳压措施,满足更高的输出质量需求。

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.
