R24P21503D 产品概述
一、概述
R24P21503D 是 YLPTEC（易川）推出的一款隔离型双路 DC-DC 转换器，输入电压为 24V，提供两路独立输出：-3V 和 15V。模块总输出功率为 2W，转换效率高达 90%，适合在体积受限且需隔离电源的工业与仪表场合作为辅助电源或偏置源使用。
二、主要参数
- 品牌：YLPTEC（易川）
- 型号：R24P21503D
- 输入电压（Vin）：24V
- 输出通道数：2
- 输出电压（Vout）：-3V、15V
- 输出电流（最大）：-3V 道 66mA；15V 道 333mA
- 总输出功率：2W
- 转换效率：90%
- 隔离电压（Vrms）：3000V
- 最大容性负载：-3V 道 680µF；15V 道 150µF
- 纹波噪声：200mVp-p
- 开关频率：50kHz
- 封装：SIP-5P，尺寸：19.5 × 9.8 × 12.5 mm
- 工作温度：-40℃ ～ +90℃
- 功能特性：短路保护、自动故障恢复
三、功能与保护
模块内置短路保护并具备自动恢复功能，在异常负载或短路解除后能自动恢复正常输出，降低系统维护复杂度。3000Vrms 的隔离能力可有效切断输入与输出间的地回路，保护被供电的模拟/数字电路免受共模干扰影响。
四、机械与环境特性
SIP-5P 小封装便于插针直插或焊接到母板上，尺寸紧凑适合空间受限的应用。工作温度范围宽（-40℃ 到 +90℃），可在工业级环境下稳定工作，但应注意在高温环境下适当降额使用以保证可靠性。
五、典型应用场景
- 工业控制器和仪表的隔离偏置源
- 通信设备的辅助电源
- 模拟前端、运放和 ADC 的参考/负电压源
- 需要小功率隔离供电的嵌入式系统
六、设计与布局建议
- 输入端建议并联合适的去耦电容，减少输入纹波并抑制瞬态电流。
- 输出端按每路最大容性负载规范布置电容：-3V 道最多 680µF，15V 道最多 150µF，避免超载导致振荡或启动问题。
- 尽量缩短高频开关回路的走线，输入与输出接地分开布置后在系统公共点汇流，以降低 EMI 干扰。
- 在高温环境下考虑散热条件，避免将模块紧贴大热源，必要时增加空气流通或散热片。
七、接线与注意事项
- 严格按照输入 24V 极性连接，防止反接损坏（若系统存在反接风险，建议在外部增加防反接保护）。
- 初次应用建议在实验台上验证输出负载、纹波及过载行为，确认短路自动恢复功能符合系统需求。
- 在特殊电磁兼容要求的系统中，配合输入滤波器和外部屏蔽以满足 EMI 规范。
八、选型与采购建议
R24P21503D 适用于要求隔离、体积小、功率在 2W 左右且需要双轨输出（含负电压）场合。采购时请确认供货方为 YLPTEC（易川）渠道或其授权代理，并核对封装与引脚定义以便直接替换或上板调试。若系统需求有额外裕量，请考虑更高功率或更高隔离等级的产品。

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.
