RT5762CHGH6F 产品概述

一、概述

RT5762CHGH6F 是 RICHTEK(台湾立锜)推出的一款高集成度降压型 DC-DC 转换器,采用降压拓扑并内置开关管与同步整流,适用于电池供电与单节锂电/多节电池降压场合。工作电压范围广(2.5V–6V),输出电压可调(0.6V–6V),最大输出电流可达 2A,开关频率 1.2MHz,封装为小尺寸 SOT-563,适合空间受限的便携设备。

二、主要参数

  • 功能类型:降压(Buck)
  • 输入电压:2.5V ~ 6V
  • 输出电压:0.6V ~ 6V(可调)
  • 输出电流:最大 2A
  • 开关频率:1.2MHz
  • 同步整流:内置(同步 MOSFET)
  • 静态电流:23µA(典型)
  • 工作温度:-40℃ ~ +125℃
  • 开关管:内置
  • 通道数:1
  • 封装:SOT-563

三、关键特性与优势

  • 高集成度:内置高侧/低侧 MOSFET,外部器件数量少,便于小型化 PCB 设计。
  • 低静态电流:23µA 待机电流有利于低功耗系统延长电池寿命。
  • 高频开关(1.2MHz):允许使用更小的电感和输出电容,缩小整体方案尺寸。
  • 宽输出范围:0.6V 至 6V 可调,适配多种负载电压需求。
  • 宽输入与温度范围:支持常见电池与工业温度等级,可靠性高。

四、应用建议与布局要点

  • 电感选型:选择饱和电流高于最大负载的电感,优先低 DCR 与屏蔽型结构以降低 EMI。
  • 输入/输出电容:建议使用 X5R/X7R 陶瓷电容,靠近芯片布置以保证环路稳定与低环路阻抗。
  • 布局注意:大电流回路(输入电容—SW—电感—输出)走短而宽的铜线,接地采用多点大面,SOT-563 热路径需要通过 PCB 过孔/铜箔散热。
  • 热管理:在满载或高 ambient 情况下注意封装温升,必要时放宽占空比或加散热层。

五、保护与可靠性

RT5762CHGH6F 具备同步整流以提升转换效率并降低发热。芯片通常包含短路保护、过温保护及欠压锁定等保护机制(具体保护行为请参照官方数据手册),便于在异常工况下保护系统与负载。

六、典型应用

  • 便携式消费电子(智能手环、蓝牙设备)
  • 电池供电的传感器与 IoT 终端
  • 车载辅助电源(符合输入电压范围)
  • 小型通信与摄像模块电源

若需电路参考、典型效率曲线或 PCB 布局范例,请提供使用电压与目标输出电流/电压,我可协助给出更具体的元件选型与参考设计建议。

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
