K7805M-1000R3 产品概述

一、产品简介

K7805M-1000R3 是 YLPTEC(易川)推出的一款升降压型开关稳压器,采用 SIP-3 封装,面向需要在宽范围输入电压下稳定输出 5V 电源的应用场景。产品已完成校验,适用于汽车、通信、工业控制及便携设备等对稳压、效率和体积有综合要求的系统。

二、主要规格

  • 功能类型:升降压型(Buck-Boost)
  • 输入电压范围:7V ~ 36V
  • 输出电压:5.0V,精度 ±3%
  • 最大输出电流:1A
  • 转换效率:最高可达 94%(典型)
  • 静态电流(Iq):典型 300µA,最大 1mA
  • 开关频率:520kHz
  • 纹波噪声:25mVp-p
  • 最大容性负载:2200µF
  • 保护功能:短路保护
  • 尺寸(L×W×H):11.6mm × 8mm × 10.4mm(SIP-3)
  • 工作温度:-40℃ ~ +85℃

三、特性与优势

  • 宽输入电压:7–36V 输入范围覆盖 12V/24V 等典型母线,适合电池与车载场景。
  • 升降压能力:输入高于或低于输出电压时均能稳定维持 5V 输出,系统可靠性更高。
  • 高效率与低功耗:94% 的高效率在中高载流时显著降低发热,静态电流低(typ. 300µA)有利于待机和节能设计。
  • 小型封装:SIP-3 体积小,便于在空间受限的模块或设备中集成。
  • 可靠保护:内置短路保护,提升系统安全性与保护外部负载。

四、典型应用场景

  • 汽车电子(车载 12V/24V 转 5V 供电)
  • 工业控制与测量设备(宽电压输入)
  • 通信与网络设备的本地稳压模块
  • 便携与远程供电装置、传感器节点和单片机供电

五、设计建议与注意事项

  • 输入/输出滤波:为保证稳压性能和低纹波,建议使用低 ESR 的陶瓷或钽电容作为输入输出滤波,并根据布局降低回流环路面积。
  • 容性负载:最大支持 2200µF 容性负载;若使用大电容,需注意启动电流与稳定性影响。
  • 散热管理:虽然效率高,但在长时间满载或高环境温度下仍需考虑散热(留意器件周围空气流通与 PCB 散热铜箔面积)。
  • EMI 与布局:520kHz 开关频率较高,布局时尽量缩短开关节点走线并加入必要的地平面与 EMI 滤波元件。
  • 保护与可靠性:结合系统设计加入保险、输入浪涌抑制等,提升整体可靠性。

六、尺寸与环境

SIP-3 紧凑封装,外形尺寸 11.6 × 8 × 10.4 mm,适合模块化安装与插座式布置。工作温度范围 -40℃ 至 +85℃,可满足典型工业级使用条件。

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
