K7803-500R3 产品概述 — YLPTEC(易川)

一、产品简介

K7803-500R3 是 YLPTEC(易川)推出的一款降压型开关稳压器模块,单路输出,固定输出 3.3V,最大输出电流 500mA。模块采用紧凑 SIP 封装(11.5 × 7.6mm),适用于输入电压范围宽、对效率和噪声有一定要求的嵌入式与工业应用。出厂校验通过,可靠性良好,适合批量应用落地。

二、主要电气参数

  • 输入电压范围:4.75V ~ 36V
  • 输出电压:3.3V,精度 ±4%
  • 最大输出电流:500mA
  • 转换效率:典型 86%(视输入电压与负载而定)
  • 静态电流(Iq):200μA
  • 开关频率:850kHz
  • 输出纹波噪声:20mVp-p
  • 最大容性负载:680μF
  • 保护特性:短路保护

三、机械与温度特性

  • 尺寸(长 × 宽 × 高):11.5mm × 7.55mm × 10.2mm
  • 封装:SIP(11.5 × 7.6mm)
  • 工作温度范围:−40℃ ~ +85℃

四、典型应用场景

  • 电池供电与便携设备(低静态电流有利于延长待机)
  • 工业控制与自动化设备(宽输入适配 12V/24V 系统)
  • 通信与物联网终端、电源模块后端稳压
  • 传感器模块、单片机供电电源

五、使用建议与布局要点

  • 输入端:建议并联 10μF~100μF 低 ESR 电容,尽量靠近 VIN 与 GND 引脚以抑制开关噪声。
  • 输出端:根据负载和纹波要求选用低 ESR 电容,最大支持 680μF;大容量电容可提升瞬态响应但会影响启动特性。
  • PCB 布局:开关节点与电感、输入/输出电容走线要尽量短且成环路,分离敏感模拟信号,地线采用独立回流或单点接地,必要时增加过孔导热。
  • 散热:在高输入电压与大负载条件下会产生热量,建议在布局时预留散热铜箔或散热 vias,必要时评估系统级温升。
  • 保护与可靠性:在有可能反接或瞬态冲击的应用中,建议外加输入反向保护或瞬态抑制器件;车载使用场景请做系统级抗扰动验证。

六、产品优势与注意事项

优势:

  • 宽输入电压范围,适配多种供电环境;
  • 体积小、效率高(典型 86%),静态电流低,适合低功耗系统;
  • 内置短路保护,提升系统安全性。

注意事项:

  • 输出电容不能超过规格上限(680μF)以免影响稳压与启动;
  • 在高温或高功率应用下注意散热与热抑制设计;
  • 若用于车载或高可靠场景,建议进行完整的 EMC/寿命验证。

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
