RT3601EAGQW 产品概述

RT3601EAGQW是台湾立锜(RICHTEK)推出的单通道同步降压转换器,专为需要高精度差分输入、高效率电源转换的场景设计,采用WQFN28小尺寸封装,集成完善的保护功能,广泛应用于服务器、工业控制、通信等领域。

一、产品定位与核心特性

RT3601EAGQW定位于中高功率密度的电源转换需求,核心特性围绕高精度、高效率、高可靠性展开:

  1. 单通道差分输入架构:支持输入电压/反馈的差分采样,有效抑制共模干扰,输出电压精度达±1%;
  2. 宽电压覆盖:输入电压范围4.5V28V,输出电压可调(0.6V24V),覆盖从低功耗MCU到高功率FPGA的供电需求;
  3. 高效率同步降压:集成低导通电阻(Rds(on))MOSFET,满载转换效率达92%以上,轻载(<10%负载)效率仍保持85%以上;
  4. 完善保护机制:内置过流保护(OCP,hiccup模式)、过压保护(OVP)、欠压保护(UVP)、热关断(TSD,150℃典型值)及软启动(SS)功能,提升系统抗异常能力;
  5. 小尺寸高密度:WQFN28封装(3mm×3mm×0.8mm),适合空间受限的高密度PCB设计。

二、关键参数规格

参数类别 具体规格 通道数 1(单通道同步降压) 输入电压范围 4.5V ~ 28V 输出电压范围 0.6V ~ 24V(可调) 最大输出电流 10A(@VIN=12V,VOUT=5V) 开关频率 固定500kHz 差分输入支持 是(反馈环路差分采样) 保护功能 OCP、OVP、UVP、TSD、SS 封装 WQFN28(3×3mm) 工作温度范围 -40℃ ~ 85℃(工业级)

三、封装与引脚功能

RT3601EAGQW采用WQFN28封装,引脚布局优化以减少寄生电感/电容,核心引脚功能如下:

  • VIN(引脚1~3):输入电压端,需并联10μF以上陶瓷电容(X7R/X5R)靠近引脚放置;
  • GND(引脚4、12、20、28):输入地端,需与散热铜箔连接;
  • SW(引脚57、1315):开关节点端,连接电感与输出电容;
  • FB(引脚11):反馈输入端(差分采样),通过分压电阻设置输出电压;
  • COMP(引脚10):环路补偿端,外接RC网络优化瞬态响应;
  • SS(引脚9):软启动端,外接电容设置启动时间(典型1ms);
  • EN(引脚8):使能端(高电平有效);
  • PG(引脚16):电源良好端(输出电压稳定后输出高电平)。

四、典型应用场景

RT3601EAGQW的宽电压范围与高可靠性使其适配多领域需求:

  1. 服务器与数据中心:CPU核心、内存DIMM、SSD存储的供电模块;
  2. 工业控制:PLC控制器、伺服驱动器、工业触摸屏的电源子系统;
  3. 通信设备:基站BBU、路由器/交换机的板级电源转换;
  4. 消费电子:高端游戏主机、笔记本电脑的GPU/CPU供电;
  5. 医疗设备:小型医疗仪器的低纹波电源(需符合医疗认证时需额外设计)。

五、应用优势与设计注意事项

5.1 应用优势

  • 抗干扰能力强:差分反馈设计可抵消PCB走线的共模噪声,适合电磁环境复杂的工业/通信场景;
  • 成本优化:集成MOSFET减少外围器件数量,降低BOM成本与PCB面积;
  • 散热性能佳:WQFN28封装的散热焊盘与PCB铜箔直接接触,满载时结温控制在120℃以内。

5.2 设计注意事项

  • 输入电容:需采用低ESR陶瓷电容,避免使用电解电容(高温下性能衰减);
  • 电感选择:优先选低DCR(<10mΩ)的屏蔽电感,减少铜损与电磁干扰;
  • 散热设计:PCB散热铜箔面积需≥10cm²(连接GND引脚),高负载时可增加散热片;
  • 反馈电阻:FB引脚的分压电阻需采用1%精度金属膜电阻,保证输出电压精度。

六、选型参考

若RT3601EAGQW无法满足需求,可参考立锜同系列替代型号:

  • 更高电流:RT3602(双通道,最大2×10A);
  • 更低电压:RT3603(输出0.5V起);
  • 更高频率:RT3605(开关频率1MHz)。

RT3601EAGQW凭借其平衡的性能与成本优势,成为中功率密度电源设计的主流选择之一。

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
