VRB1212S-6WR3 DC-DC电源模块产品概述

一、核心性能参数梳理

VRB1212S-6WR3是YLPTEC(易川)推出的单通道DC-DC电源模块,核心参数精准适配多场景供电需求:

  • 输入输出基础参数:输入电压(Vin)覆盖9V~18V宽范围,输出电压(Vout)稳定12V,最大输出电流500mA,额定功率6W,满足小功率负载的核心供电要求;
  • 效率与纹波:转换效率达85%,降低模块自身发热,提升长期可靠性;输出纹波噪声低至50mVp-p,为敏感电路提供纯净电源;
  • 电气防护与隔离:内置短路保护功能,避免负载短路对模块及系统的损坏;隔离电压达1.5kVrms,满足电气隔离设计要求;
  • 环境与动态参数:工作温度范围-40℃~+85℃,适应工业/车载等宽温场景;开关频率312.5kHz(高频设计),利于缩小模块体积;最大容性负载470uF,兼容大容性负载启动。

二、关键技术特性

  1. 短路保护机制:模块内置过流保护电路,输出短路时自动启动保护,故障排除后可自行恢复,无需手动重置;
  2. 高隔离设计:1.5kVrms隔离电压有效阻断输入输出间的电气干扰,适合对隔离要求高的工业、车载等场景,保障系统稳定性;
  3. 宽输入电压覆盖:9V~18V兼容12V车载电源、18V工业适配器及电池供电系统,适配性强;
  4. 低纹波输出:50mVp-p纹波噪声远低于同类小功率模块,可直接为传感器、模拟电路、射频前端等敏感负载供电;
  5. 高频紧凑设计:312.5kHz开关频率无需大体积电感/电容,配合SIP封装实现小型化,节省系统空间。

三、封装与物理特性

VRB1212S-6WR3采用SIP(单列直插)封装,物理尺寸为22mm(长)×9.5mm(宽)×12mm(高),体积小巧紧凑,适合空间受限的电路板设计;
SIP封装引脚布局便于手工/自动焊接,安装便捷,且额定功率6W、效率85%,发热可控,无需额外散热片。

四、典型应用场景

  1. 工业自动化控制:为PLC I/O模块、工业传感器(温度/压力传感器)供电,宽温范围适应车间高低温,隔离设计避免现场干扰;
  2. 车载电子设备:适配12V/24V车载电源(18V为24V系统波动范围),为车载显示屏、摄像头、传感器节点供电,短路保护保障行车安全;
  3. 通信终端:为LoRa网关、Wi-Fi节点的射频前端/基带电路供电,低纹波满足射频信号纯净度要求;
  4. 物联网节点:为电池供电的IoT终端(智能电表、环境监测节点)提供12V稳定电源,宽输入兼容3节锂电池(11.1V)或18V适配器;
  5. 小型医疗设备:为便携式医疗仪器(血糖监测仪、小型输液泵)控制电路供电,宽温与隔离设计符合可靠性要求(注:医疗认证需额外确认)。

五、使用注意事项

  1. 输入电压限制:严格控制Vin在9V~18V内,过压(>18V)损坏模块,欠压(<9V)无法稳定输出;
  2. 负载电流限制:最大输出电流≤500mA,持续过载加剧发热,降低使用寿命;
  3. 容性负载控制:输出容性负载≤470uF,超量可能影响启动或纹波性能;
  4. 温度范围:工作温度需在-40℃~+85℃内,超出可能输出不稳定或失效;
  5. 隔离安全:1.5kVrms为额定隔离电压,需确保模块与其他电路绝缘距离符合设计要求,避免击穿。

总结

VRB1212S-6WR3凭借宽输入、高隔离、低纹波、短路保护及紧凑封装等特性,成为工业控制、车载电子、物联网等领域小功率电源设计的可靠选择,适配多场景需求且具备良好可靠性与稳定性。

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
