一、核心定位与目标应用

该器件定位于高性能中等功率降压转换,主要服务于需要稳定供电、低待机功耗及宽温可靠性的场景:

  • 工业控制:PLC、传感器、电机驱动模块的电源转换;
  • 通信设备:RRU、小型基站、光纤收发器的供电;
  • 车载电子:中控系统、ADAS传感器、车载充电器;
  • 便携设备:高功率移动电源、户外储能、笔记本电源适配器;
  • 消费电子:高性能游戏机、智能电视的功率模块。

二、关键性能参数解析

XR76108ELTR-F的核心参数针对实际应用场景优化,关键特性如下:

  1. 宽输入电压范围:4.5V22V,兼容12V/24V工业电源、34节锂电池(满电21.6V)等常见输入源,无需额外电压转换;
  2. 高输出电流:8A连续输出,满足FPGA、微处理器、功率放大器等中等功率负载的供电需求;
  3. 可调开关频率:200kHz~800kHz,可平衡效率与元件尺寸——低频(200kHz)提升满载效率,高频(800kHz)缩小电感/电容,适配紧凑设计;
  4. 低静态电流:1.3mA,轻载或待机状态下功耗低,适合电池供电设备的低待机需求;
  5. 同步整流内置:集成同步整流管,替代外置续流二极管,降低导通损耗,典型满载效率达92%以上;
  6. 宽结温范围:-40℃~+125℃,符合工业级环境要求,可稳定工作于极端温度场景。

三、拓扑结构与内置功能

  1. 降压式拓扑:采用成熟稳定的同步降压拓扑,输出电压低于输入电压,适合多数降压供电场景;
  2. 全内置功率管:集成高压侧与低压侧开关管(同步整流管),无需外置功率器件,简化电路设计;
  3. 可调输出电压:通过外部电阻分压设置输出电压(范围0.8V~20V),适配不同负载的电压需求;
  4. 保护功能:内置过流保护(OCP)、过温保护(OTP)、软启动(SS),防止负载异常、电源波动或器件过热损坏。

四、封装与可靠性设计

  1. 小尺寸封装:采用30-QFN(5×5mm)封装,厚度薄、引脚间距合理,适合高密度PCB布局,满足设备小型化趋势;
  2. 宽温可靠性:结温范围覆盖-40℃~+125℃,通过工业级可靠性测试,可稳定工作于户外、车载等极端环境;
  3. 集成度优势:内置同步整流管及保护电路,减少外部元件数量,降低BOM成本及故障点,提升系统可靠性。

五、设计优势总结

XR76108ELTR-F在性能与实用性上的平衡,使其成为多款应用的优选器件:

  • 适配性强:宽输入范围与可调输出/频率,覆盖多场景需求;
  • 效率与尺寸兼顾:可调频率可灵活优化效率或缩小元件;
  • 低待机功耗:1.3mA静态电流适合电池供电设备;
  • 可靠性高:内置保护功能与宽温特性,减少系统故障风险;
  • 集成度高:内置功率管简化设计,降低成本。

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
