P2576L-50-TQ5-R 产品概述
一、产品简介
P2576L-50-TQ5-R 是友顺（UTC）推出的一款内置开关管的降压型 DC-DC 转换器，封装为 TO-263-5（DPAK 风格大功率贴片）。器件针对宽输入电压域与中等电流输出场合设计，能以紧凑方案提供稳定的 5.0V 输出，最大输出电流可达 3A，适合多种嵌入式与工业电源应用。
二、主要规格
- 功能类型：降压型（Buck）
- 输入电压范围：7V ~ 40V
- 输出电压：5.0V（固定）
- 最大输出电流：3A
- 开关频率：52kHz
- 工作温度范围：-40℃ ~ +125℃
- 静态电流（Iq）：约 5mA
- 开关管：内置
- 输出通道数：1 路
- 封装：TO-263-5
- 品牌：UTC（友顺）
三、关键特性与优势
- 宽输入范围覆盖常见工业与通信电源轨，简化上游电源设计；
- 内置功率开关，减少外部器件数量与 PCB 占用；
- 低静态电流有利于待机能耗控制；
- 中等开关频率（52kHz）在效率与器件损耗之间取得平衡，便于散热管理；
- TO-263-5 大功率封装，利于热量传导与高可靠性应用。
四、典型应用场景
- 工业控制与仪表电源；
- 网络与通信设备辅助电源；
- 嵌入式系统与单板计算模块；
- 车载辅助电源（需配合瞬态抑制与车规级设计）。
五、设计与布局建议
- 输入端推荐使用低 ESR 的旁路电容（如陶瓷 + 钽电容或电解）以抑制尖峰与纹波；
- 输出侧选用低 ESR 大容量滤波电容以稳定负载瞬态；
- 选用额定电流高于 3A、低 DCR 的电感，注意饱和电流裕量；
- TO-263-5 封装需良好散热：在 PCB 热铜区域使用加宽铜迹与多过孔导热到下层；
- 布线时将开关节点走线最短，输入地与功率地分区，参考器件数据手册的推荐布局图。
六、保护与可靠性
器件适配常见系统级保护设计。具体的过流、过温和短路保护特性请以官方数据手册为准，在关键应用场合建议做系统级冗余与保护设计以提高可靠性。

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.
