K7805-500R3 产品概述

一、产品简介

K7805-500R3 是 YLPTEC(易川)推出的一款升降压型(buck‑boost)直流电源模块,单路输出,提供 ±5V(有 +5V 与 -5V 两个版本)稳压供电解决方案。该模块输入电压范围宽(6.5V~36V),在电池供电与工业电源场景中均能稳定工作,适合对体积、效率和可靠性有要求的嵌入式与工业控制应用。

二、主要性能参数

  • 功能类型:升降压型(Buck‑Boost)
  • 输出通道数:1
  • 工作电压 Vin:6.5V ~ 36V
  • 输出电压 Vout:+5V(版本一) / −5V(版本二)
  • 输出电流(最大):+5V 版本 500mA;−5V 版本 300mA(极性为负)
  • 输出电压精度:±2%
  • 转换效率:+5V 版本 ≈ 90%;−5V 版本 ≈ 81%
  • 最大容性负载:+5V 版本 680µF;−5V 版本 330µF
  • 静态电流 Iq:200µA
  • 纹波噪声:20mVpp
  • 保护特性:短路保护
  • 封装形式:插件(Through‑Hole)
  • 外形尺寸(L×W×H):11.5mm × 7.55mm × 10.2mm
  • 工作温度范围:−40℃ ~ +85℃

三、产品特点

  • 宽输入电压范围:6.5V~36V,可兼容多种电源(铅酸、锂电池组及工业供电)。
  • 升降压构架:输入电压可在高于或低于输出电压时稳定输出,对电池放电过程中电压变化具有良好适应性。
  • 低静态电流:200µA 的静态电流利于电池供电的低功耗设计。
  • 高效率:+5V 版本高达约 90% 的转换效率,有助于降低发热与延长续航。
  • 短路保护:内置保护功能,提高系统可靠性与安全性。
  • 紧凑插件封装:便于在传统电路板上安装、测试与更换。

四、典型应用场景

  • 便携式与电池供电设备(需稳定 ±5V 的模拟/数字电路)
  • 工业控制与数据采集模块(现场总线或传感器供电)
  • 仪表与通信设备的局部稳压电源
  • 需要在宽电压范围内保持固定 5V/−5V 电源的系统

五、使用与选型建议

  • 版本选择:若系统需要正 5V,请选 +5V 版本(最大 500mA);若需要负 5V,请选 −5V 版本(最大 300mA)并注意极性。
  • 输入电源要求:确保输入电源在 6.5V 至 36V 范围内;对于长时间高电流工作,建议留出额定余量,避免输入电压接近上下限。
  • 输出负载与滤波:输出可驱动较大容性负载,但不要超过对应版本的最大容性负载(+5V 680µF,−5V 330µF)。推荐在输入端并联合适的低 ESR 电解电容作旁路,并在靠近引脚处放置 0.1µF 陶瓷电容以抑制高频噪声。
  • PCB 布局与散热:插件封装虽便于安装,但模块在满载时仍会产生热量。布线时应保证输入、输出及地回路短且粗,必要时在散热面积允许的位置增加铜箔以利散热。
  • 保护与可靠性:模块具备短路保护,但不应依赖单一防护措施。推荐配合熔断器或限流电路一道使用以提高系统安全性。

六、测试与注意事项

  • 上电测试:首次上电建议在无负载或轻负载条件下确认输出电压,再逐步增加负载观察模块温升与输出稳定性。
  • 纹波与噪声测量:纹波噪声指标为典型 20mVpp,测量时请使用接地良好的示波器及 10:1 探头,短接探头地环以避免测量误差。
  • 环境条件:工作温度为 −40℃ ~ +85℃,在高温或高湿环境下使用时应确保通风与防护措施,以免缩短寿命或影响可靠性。

七、封装与订购信息

  • 品牌:YLPTEC(易川)
  • 封装:插件(Through‑Hole)
  • 尺寸:11.5mm × 7.55mm × 10.2mm
  • 在选型和采购时,请确认所需输出极性(+5V 或 −5V)与最大电流需求,以保证模块在工作点内长期可靠运行。

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
