K7803M-1000R3 产品概述

一、产品简介

K7803M-1000R3 是 YLPTEC(易川) 推出的降压型开关稳压模块,输入电压范围宽(6V~36V),输出固定 3.3V,额定输出电流 1A。模块采用高频开关设计,典型转换效率可达 90%,静态电流仅 300µA,体积小(SIP 封装,11.6×7.5×10.2mm),无需外加散热片即可在工业环境中可靠工作。

二、主要电气参数

  • 功能类型:降压型(Buck)
  • 输入电压(Vin):6V ~ 36V
  • 输出电压(Vout):3.3V,精度 ±1%
  • 最大输出电流:1A
  • 转换效率:约 90%
  • 静态电流(无载):300µA
  • 纹波噪声:50mVp-p(典型)
  • 开关频率:850kHz
  • 最大容性负载:2200µF
  • 工作温度范围:-40℃ ~ +85℃

三、保护与可靠性

模块内置短路保护与自动故障恢复功能,能在过流或短路后自动限制输出并在故障解除后恢复工作,提升系统可靠性。宽温设计与低静态电流使其适合长期连续运行的工业应用场景。

四、应用场景

该系列模块是三端线性稳压器的高效替代品,特别适用于工控系统、电力监控、电源模块、仪器仪表、嵌入式设备等需要从较高总线电压降至 3.3V 的场合。由于效率高、发热低,可用于空间受限且散热条件有限的设备中。

五、设计与使用建议

  • 输入侧建议并联低 ESR 电解/钽电容与陶瓷去耦,以抑制输入瞬态与降低 EMI。
  • 输出侧可根据负载动态选择合适容量的稳压电容,模块支持高达 2200µF 的容性负载,但应优先使用低 ESR 元件以获得最佳纹波与稳定性。
  • 高频开关工作,布局时注意输入/输出回路短且宽,避免长回路揉入噪声,必要时加入滤波网络降低干扰。
  • 在严苛环境或靠近敏感模拟电路时,应考虑额外的 EMI 抑制措施(共模电感、屏蔽等)。

六、外形与封装

封装形式:SIP,尺寸 11.6×7.5×10.2mm,便于板上直接插装或空间受限的模块化设计。

K7803M-1000R3 以其高效、低损耗、稳健的保护特性,成为替代传统线性稳压器的理想选择,特别适合工业与仪表类电源设计需求。品牌:YLPTEC(易川)。

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
