XL7025E1 降压型DC-DC电源芯片产品概述

XL7025E1是芯龙半导体(XLSEMI)推出的宽输入范围降压型DC-DC电源芯片,针对中高压输入、中等功率输出场景优化,具备高集成度、宽温适应性等特点,广泛适用于汽车电子、工业控制等领域。

一、产品定位与核心优势

XL7025E1定位为高性价比宽压降压解决方案,核心优势集中在以下几点:

  1. 宽电压覆盖:支持10V80V宽输入,兼容12V/24V/48V等主流系统;输出1.25V20V连续可调,覆盖3.3V、5V、9V等常见低压需求;
  2. 内置功率管:无需外置MOSFET,简化电路设计,降低BOM成本;
  3. 低待机功耗:静态电流仅2.5mA,适合对待机功耗敏感的应用(如车载休眠模式);
  4. 宽温可靠性:结温支持-40℃~+125℃,满足汽车、工业等极端环境要求;
  5. 稳定开关频率:150kHz固定频率,平衡效率与外围元件体积,电感电容选型更灵活。

二、关键电气参数解析

XL7025E1的参数针对实际场景做了针对性优化,核心参数如下:

1. 输入输出特性

  • 输入电压:10V~80V(覆盖12V车载系统、24V工业设备、48V电动车辅助电源);
  • 输出电压:1.25V~20V(通过FB脚分压电阻调节,基准电压1.25V);
  • 输出电流:600mA(满足大多数传感器、MCU、小功率模块的供电需求)。

2. 功耗与效率

  • 静态电流:2.5mA(无负载时功耗低,适合长期待机场景);
  • 开关频率:150kHz(固定频率,避免EMI漂移,外围元件体积适中);
  • 典型效率:90%以上(降压拓扑结构,能量转换损耗低)。

3. 环境适应性

  • 结温范围:-40℃~+125℃(符合AEC-Q100汽车级标准,工业级宽温要求);
  • 拓扑结构:降压式(Buck),结构简单,抗干扰能力强。

三、封装与引脚功能

XL7025E1采用TO-252-5贴片封装(5脚),体积小巧(6.5mm×8.0mm),散热性能优异,适合PCB高密度布局。引脚功能如下:

引脚编号 引脚名称 功能说明 1 VIN 输入电压端(10V~80V) 2 GND 公共地端 3 FB 反馈调节端(接VOUT分压电阻,调节输出电压) 4 SW 开关输出端(接电感) 5 VOUT 输出电压端(1.25V~20V)

四、典型应用场景

XL7025E1的宽电压、宽温特性使其适用于多个领域:

  1. 汽车电子:车载传感器(胎压监测、温度传感器)、车身控制器小功率模块、12V/24V车载电源转换;
  2. 工业控制:PLC模块供电、工业传感器(压力、流量)供电、分布式电源系统(48V转5V/12V);
  3. 消费电子:高压输入充电器扩展智能电表辅助电源;
  4. 通信设备:基站辅助电源、小功率通信模块供电。

五、典型应用电路说明

XL7025E1的电路简洁,核心元件仅需电感、电容、分压电阻:

  1. 输入滤波:VIN脚接10μF电解电容+0.1μF陶瓷电容,滤除输入纹波;
  2. 输出调节:FB脚接VOUT与GND之间的分压电阻(Rtop与Rbottom),输出电压公式为:
    ( V_{OUT} = 1.25V \times (1 + \frac{R_{top}}{R_{bottom}}) )
    例:需输出5V时,选Rbottom=10kΩ,Rtop=30kΩ;
  3. 功率回路:SW脚接10μH~22μH低DCR电感,电感另一端接VOUT脚;VOUT脚接10μF电解电容+0.1μF陶瓷电容,滤除输出纹波;
  4. 接地要求:GND脚需与PCB地平面可靠连接,减少噪声干扰。

六、总结

XL7025E1以高集成度、宽适应性、低功耗为核心亮点,解决了中高压输入场景下的低压供电问题,尤其适合汽车、工业等对可靠性要求高的领域。其简洁的电路设计与灵活的选型,能有效降低系统开发成本与体积,是同类应用的优选方案。

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
