K7812-500R3 产品概述

一、产品简介

K7812-500R3 是 YLPTEC(易川)推出的一款降压型开关稳压模块,采用 SIP 封装,面向工业级电源转换需求。该型号为 +12V、500mA 输出版本,输入电压范围宽(15V~36V),适用于 24V 电源轨的降压供电场合,兼顾高效率与低静态功耗,便于插装与批量化生产。

二、主要电气参数

  • 功能类型:降压型(Step-down)
  • 输入电压(Vin):15V ~ 36V
  • 输出电压(Vout):+12V(K7812-500R3)
  • 输出电流(最大):500mA
  • 输出电压精度:±2%
  • 转换效率:典型 94%
  • 最大容性负载:330µF(对应 +12V/500mA 版本)
  • 静态电流(Iq):200µA
  • 纹波噪声:20mVp-p(典型)
  • 保护特性:短路保护
  • 工作温度:-40℃ ~ +85℃
  • 封装:SIP,品牌:YLPTEC(易川)

(注:同系列还有 -12V / 150mA 等负电压版本,性能参数略有差异。)

三、性能亮点

  • 高效率:94% 的典型转换效率在 12V/500mA 条件下可将输出功耗损耗控制在约 0.4W(示例:Vout·Iout = 6W,损耗约 0.38W),有利于降低温升与系统总能耗。
  • 低静态电流:Iq 仅 200µA,适合待机功耗敏感或电池供电场合。
  • 容易使用:SIP 封装支持插装/焊装,系统集成方便。
  • 稳健保护:内置短路保护,提高系统可靠性并简化外围保护电路设计。

四、封装与热设计建议

SIP 封装适合通用 PCB 插装,但 500mA 持续工作时仍需关注散热与环境温度:

  • 推荐在 PCB 上为模块预留散热面积并保证一定自然对流,必要时在高环境温度或紧凑安装中增加空气流动或散热片。
  • 在 24V 输入、满载工作下模块自身损耗约 0.3~0.5W,通常无需额外散热,但在 85℃ 环境或并联多模块时需做电流/温度降额处理。

五、典型应用场景

  • 工业控制系统(24V 到 12V 传感器、继电器供电)
  • 通信设备与嵌入式平台电源降压
  • 仪器仪表、测控模块供电
  • 车载及移动供电系统(注意满足工作温度与防护要求)

六、使用与布局注意事项

  • 输入侧建议并联一只低 ESR 电解电容与一只 0.1µF 陶瓷近端旁路,以抑制开关噪声。
  • 输出侧根据最大容性负载不超过 330µF,建议并联陶瓷去耦以降低高频纹波。
  • 布局时将输入电容尽量靠近模块输入端,输出电容靠近输出端,地线短且粗以降低回路阻抗。
  • 具体引脚排列、安装孔位与电气引脚定义请参照产品数据手册以避免误接。

七、订购信息与资料

型号说明:K7812-500R3 表示 +12V 输出、500mA 版本。订购或批量采购请提供完整型号并确认版本(正/负输出、电流等级)。如需详细电气特性曲线、典型应用电路或封装图纸,请索取 YLPTEC 原厂数据手册或联系经销商获取样品与技术支持。

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
