K7803-2000R3 概述
K7803-2000R3 是 YLPTEC（易川）推出的一款降压型开关稳压模块，面向工业级电源与嵌入式应用。该模块集成高效 DC-DC 降压变换器，采用工业标准 SIP-3 封装，兼顾体积小、效率高与可靠性，适合对体积与功耗有较高要求的场合。
一、主要功能与特点
- 输出类型：固定输出 3.3V，输出精度 ±1%。
- 输出能力：最大连续输出电流 2A，最大容性负载可达 1800µF，适应大电容滤波负载。
- 保护特性：具备输出短路保护并自动恢复，提升系统安全性与可靠性。
- 引脚兼容：机械、电气引脚兼容 LM78xx 系列三端线性稳压器，便于替换与设计迁移。
- 低空载电流：静态电流约 200µA（typ），利于节能与待机功耗控制。
二、电气性能（资料汇总）
- 输出电压：3.3V（±1%）。
- 输入电压：资料中标注为 4.5–30V（描述部分）与 6–36V（参数部分），实际使用请以正式数据手册或样品确认为准。
- 转换效率：典型效率高，资料中给出典型值可达 96%，另有场景标注 89%；效率受输入电压、负载电流和外部元件影响。
- 纹波噪声：约 45mV p-p（典型）。
- 开关频率：2.4MHz，高开关频率有利于减小外部磁性元件与滤波电容体积。
- 工作温度：-40℃～+85℃，适合工业级温度要求。
三、封装与尺寸
- 封装形式：工业标准 SIP-3（引脚排列兼容三端线性稳压器）。
- 尺寸：约 11.5×9mm（部分资料列为 11.6×7.5×10.2mm），小巧便于模块化与高密度布局。
四、典型应用领域
电力、工业控制、通信设备、物联网终端、车载电子和轨道交通等需要稳固 3.3V 电源的领域。特别适合需要低待机电流与较高转换效率的便携式或长期运行设备。
五、设计与使用建议
- 输入滤波：为抑制输入纹波与保障稳定性，建议在模块输入端并联低 ESR 电解/固态电容与陶瓷旁路电容。
- 输出滤波与容性负载：模块支持高达 1800µF 的容性负载，但过大电容或不合适的 ESR 可能影响启动与环路稳定性，建议参考样片测评确定最佳输出电容与 ESR 匹配。
- 散热与热设计：在大电流输出或高压差工况下应关注模块温升，必要时预留导热铜箔或散热空间。
- EMC 与布局：2.4MHz 开关频率要求短回流路径与良好接地，输入与输出滤波器元件尽量靠近模块引脚焊接。
- 验证与选型：由于资料中对输入电压范围与效率存在不同表述，量产前务必索取并核对正式数据手册与工程样片，进行完整的环境与老化测试。
K7803-2000R3 综合了高效率、小体积与工业级可靠性，适合需要稳健 3.3V 电源解决方案的各类嵌入式与工业应用。需要详细电气特性曲线或原理图建议联系 YLPTEC 获取完整数据手册。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
