二、功能特性

  • 短路保护:内置过流/短路保护机制,确保在异常负载或短路情况下模块安全降功率或限流。
  • 自动故障恢复:触发保护后模块自动重试恢复输出,避免手动干预。
  • 支持负输出:模块设计支持负输出应用(按具体接线或外部配置实现)。
  • 高可靠性:宽温度和工业级封装适配恶劣环境与长期连续运行。

三、产品优势

  • 宽输入范围:15–36V 输入覆盖常见车载、工控及中等电压总线,适应性强。
  • 高效率与低发热:高达 96% 的转换效率在 1A 的输出能力下尽量降低功耗与热量,利于散热管理和系统可靠性。
  • 低待机电流:300 µA 静态电流适用于需长时间在线且关注空载损耗的应用。
  • 良好负载驱动能力:支持 1000 µF 大容性负载,适配有电容性耦合或滤波需求的负载特性。
  • 紧凑封装:SIP-3 封装便于模块化设计与插针安装,节省 PCB 布局空间,便于批量生产与更换维护。

四、典型应用场景

  • 电力与配电监控设备:为控制板、传感器或通信模块提供稳定 12V 电源。
  • 工业控制与自动化:驱动 PLC 扩展模块、采集模块及边缘控制单元。
  • 通信与物联网网关:为无线模组、以太网接口及外围设备提供低噪声电源。
  • 汽车与轨道交通电子设备:适用于车载电子、监测单元及轨道通信设备(需按整车/车辆认证考虑使用)。

五、封装与环境适配

  • 封装:工业标准 SIP-3,便于插装与散热处理。
  • 尺寸:长 11.6 mm × 宽 7.5 mm × 高 10.2 mm,适合空间受限的嵌入式系统。
  • 温度适应:-40℃ 到 +85℃,满足工业与车载级温度循环与高低温运行要求。

六、选型与设计注意事项

  • 输入去耦:建议在模块输入端靠近引脚放置低 ESR 电解/陶瓷输入电容以抑制输入纹波和瞬态冲击。
  • 输出滤波:根据系统对纹波的敏感度选择合适的输出电容与滤波网络,最大容性负载 1000 µF 内可用。
  • 散热考虑:在接近最大输出电流或高温环境下注意模块周边的散热路径,尽量保证空气流通或加装散热片。
  • 保护与测试:开发阶段进行短路、过载、温升及纹波测试,验证自动故障恢复特性及长期稳定性。
  • 接地与布局:输入输出回路要尽量短且粗,接地良好以降低噪声耦合和电磁干扰。

K7812M-1000R3 提供了一种体积小、效率高且适用范围广的工业级升降压电源解决方案,适合对稳定性与可靠性有较高要求的 12V 电源设计场合。若需详细电气特性曲线、引脚定义或评估样片,可联系 YLPTEC(易川) 获取完整数据手册与参考设计。

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
