XL1507A-5.0E1 产品概述

一、产品概述

XL1507A-5.0E1 是一款降压型(Buck)开关稳压器,集成功率开关管,固定输出 5.0V,输出电流可达 3A。输入电压范围宽:4.5V 至 50V,开关频率 150kHz,工作温度 -40℃ 至 +125℃。器件为非同步整流结构,内置开关管并带有过流保护,静态电流仅 1.3mA,适合需要高输入耐受能力与中等功率输出的电源设计场合。品牌为 XLSEMI(芯龙),封装为 TO-252(DPAK),便于表面贴装与热管理。

二、主要性能特点

  • 宽输入电压:4.5V–50V,支持 12V、24V、48V 等多种系统电源。
  • 固定输出:5.0V,最大输出电流 3A。
  • 开关频率:150kHz,权衡了效率与元件体积。
  • 内置开关管:简化外部器件数量与PCB设计。
  • 非同步整流:需外接肖特基二极管作为续流元件以保证低压降与可靠性。
  • 低静态电流:Iq = 1.3mA,适合对待机损耗有要求的应用。
  • 保护功能:具备过流保护,提高系统可靠性。

三、典型应用场景

  • 工业控制与自动化设备(广泛输入电压)。
  • 通信设备、基站辅助电源。
  • 汽车电子及车载电源(需配合输入浪涌抑制)。
  • 仪器仪表、嵌入式系统电源模块。

四、设计与选型要点

  • 续流二极管:由于为非同步整流,请选用低VF、高速肖特基,电流与功耗需满足峰值电流要求。
  • 电感选择:电感额定电流应大于 3A,考虑 20%–40% 的纹波电流设计以降低峰值应力与噪声。
  • 电容要求:输入/输出使用低 ESR 的陶瓷或固态电容,以抑制纹波与改善稳定性;输入电容应靠近 VIN 与 GND 布局。
  • PCB 布局:缩小功率回路环路面积,确保散热铜箔充足,TO-252 背部与铜地连通以利于散热。
  • 热设计:高功率工况下注意器件结温,不同封装与散热条件下可能需要降额使用。

五、封装与工作环境

封装为 TO-252(DPAK),适合表面贴装与机器装配。工作温度范围 -40℃ 至 +125℃,适用于工业级环境,但在车规或高温密集布置时应验证实际热阻与温升并做必要的保护与散热设计。

总结:XL1507A-5.0E1 提供宽输入、电流能力中等、外部元件需求较少的稳压解决方案,适合各种需要稳健降压转换且输入电压波动较大的应用场合。

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
