IB2405S-2W是YLPTEC(易川)推出的小功率非隔离降压型DC-DC电源模块,专为24V工业电源系统设计,目标场景聚焦于对体积、可靠性、宽温适应性有明确要求的工业控制、物联网终端及小型嵌入式系统领域。该模块无需额外外围电路即可实现稳定5V输出,能有效简化电源设计流程,降低系统成本。
模块采用宽输入电压范围设计,输入电压(Vin)覆盖22.8V~25.2V,精准匹配工业常用24V直流电源的±5%波动区间,避免因电源电压波动导致输出不稳定;输出电压(Vout)稳定在5V,最大输出电流(Iout)为400mA,额定输出功率2W,满足中小功率负载的供电需求。
转换效率达72%,在同功率段降压模块中处于中等偏上水平,能有效减少自身发热,降低散热要求;输出纹波噪声控制在50mVp-p(典型值),对于5V输出系统而言,该噪声水平可满足大多数数字电路、传感器等对电源噪声敏感的应用场景,无需额外增加滤波电路即可稳定工作。
开关频率固定为100kHz,属于中低频段,电磁干扰(EMI)辐射相对较低,符合一般工业设备的EMC要求;支持最大100uF的容性负载,可兼容后级电路的滤波电容,进一步降低输出纹波,提升负载瞬态响应能力。
内置输出短路保护机制,当负载端出现短路故障时,模块可自动进入限流模式或切断输出,避免模块自身及负载损坏,提高系统抗故障能力,降低维护成本。
工作温度覆盖-40℃~+85℃,符合工业级产品的温度标准,可适应户外低温环境(如北方冬季)、高温车间(如冶金、化工现场)等极端温度场景,无需额外的温度补偿电路。
采用SIP-4直插式封装,体积仅为19.5mm(长)×10mm(宽)×7mm(高),体积小巧,适合紧凑布局的PCB设计,尤其适用于小型嵌入式设备、传感器节点等空间受限的应用。
IB2405S-2W相比同类小功率降压模块,具备以下核心优势:
该模块凭借稳定的性能与紧凑的设计,成为24V转5V小功率供电场景的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
