K7809-500R3 产品概述
一、产品简介
K7809-500R3 是 YLPTEC(易川) 出品的一款降压型开关稳压模块，单路输出、额定输出电压为 9V，最大输出电流 500mA。模块输入电压宽范围为 12V~36V，适用于中高压向稳定 9V 轨供电的场合。校验通过!
二、主要参数
- 功能类型：降压型（Buck）
- 输入电压：12V–36V
- 输出电压：9V，精度 ±2%
- 输出电流：最大 500mA
- 转换效率：最高 93%（典型工作点）
- 静态电流（Iq）：200µA
- 纹波噪声：20mVp-p（典型）
- 最大容性负载：680µF
- 工作温度：-40℃ ~ +85℃
- 特性：短路保护
三、性能与保护
高达 93% 的转换效率可显著降低功耗与热量产生，静态电流仅 200µA 有利于待机能耗控制。内置短路保护提高系统可靠性，遇过流或输出短路时能够限制输出并自恢复，适合对供电安全性有要求的嵌入式设备。
四、封装与热管理
模块采用 SIP 封装，外形尺寸约 11.5×7.6mm，体积小、便于插装或焊接于 PCB。尽管效率高，仍建议在高负载或高环境温度下考虑散热设计：在模块底部或附近留出散热铜地、增加过孔或保证空气对流，以维持长期稳定工作。
五、典型应用
适用于工业控制、仪表、通信终端、小型控制柜、电源模块和便携式设备等需将 12–36V 降至稳定 9V 的场景，尤其对容性负载较大（≤680µF）或需短路保护的系统更为合适。
六、使用建议与注意事项
- 输入端建议并联低 ESR 电解或固态电容以抑制输入尖峰；输出端使用不超过规格的电容并保证 ESR 在推荐范围内。
- 布局时输入、输出与地线尽量短而粗，开关节点远离敏感模拟电路以降低干扰。
- 超过额定电流、输入超压或长期高温工作会影响寿命，应在规格范围内设计余量。
本产品适配多种工业与消费类供电需求，结合合理布局与散热，可稳定可靠地提供 9V 输出。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
