RT6273BHGJ6F 产品概述

一、产品简介

RT6273BHGJ6F 是台湾立锜(RICHTEK)推出的一款高集成度降压型开关稳压器,采用降压(Buck)拓扑、内置功率开关,工作电压范围宽(VIN = 4.5V ~ 17V),输出电压可调(VOUT = 0.765V ~ 7.0V),最大输出电流可达 3A。开关频率为 1.4MHz,静态电流仅 280μA,支持同步整流以提升转换效率,工作温度范围 -40℃ 到 +125℃,封装为小型 TSOT-23-6,适合空间受限的便携与工业应用。

二、主要特性

  • 输入电压:4.5V ~ 17V,适配多种电源输入场景(电池、汽车、工业总线等)。
  • 输出电压可调:0.765V ~ 7.0V,适用于多种芯片供电需求。
  • 最大输出电流:3A,满足中等功率负载。
  • 开关频率:1.4MHz,有利于使用小体积电感与电容,降低整体 PCB 面积。
  • 同步整流:提高轻载及全负载效率,降低功率损耗。
  • 低静态电流:Iq = 280μA,适合需低待机功耗的系统。
  • 内置高侧/低侧开关,简化外围元件选型与布局。
  • 工作温度:-40℃ ~ +125℃,满足工业级环境要求。

三、典型应用

  • 便携式设备电源(平板、手持终端、便携仪器)。
  • 工业控制与通信设备的局部降压供电。
  • 点烟器/车载电源、后备电源模块(需注意热管理与输入瞬态)。
  • 电池供电系统与电源管理模块。

四、设计与应用建议

  • 外围元件:建议配合低 ESR 输入/输出电容和适配于 1.4MHz 的功率电感。尽量选用额定电流高于 3A 的电感与电容以保证余量与可靠性。
  • 布局要点:输入电容应靠近 VIN 与 GND 引脚以减少回流环路;开关节点(SW)走线要短且远离模拟/反馈走线;输出电感与输出电容布置紧凑以降低纹波。
  • 散热:TSOT-23-6 体积小,散热能力有限,建议在 PCB 下方做较大铜箔或多盏过孔连接至内部大地铜层以提高散热性能。
  • 保护与可靠性:设计时预留短路保护、过流及热关断等机制;对输入瞬态(例如汽车启动)考虑抑制与保护电路。

五、封装与采购信息

  • 封装:TSOT-23-6,适合空间受限的应用板。
  • 建议在 BOM 中标注器件完整型号(RT6273BHGJ6F)并参考制造商数据手册确认管脚定义与典型电路以免引脚误配。

六、总结

RT6273BHGJ6F 以高集成度、宽输入电压与可调输出电压的组合,适用于需要小体积、高效率、低静态功耗的降压电源场景。合理选择外围被动元件与优化 PCB 布局后,可实现稳定的 3A 输出与优良的热稳定性。有关详细典型电路、管脚定义与电气特性,请参考立锜官方数据手册以完成最终设计验证。

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
