RT8288AZSP 产品概述

RT8288AZSP 是 RICHTEK(立锜)推出的一款高性能单通道降压型同步整流 DC-DC 转换器,适用于对功率密度、效率与稳压精度有较高要求的点对点供电与系统电源管理场合。芯片采用降压拓扑、内置功率开关,并提供可调输出,便于实现从低压核心电压到中高压外设电源的灵活输出。

一、主要规格与功能亮点

  • 输入电压范围:4.5V ~ 21V,适配宽输入场景(如 12V/24V 总线、互联设备、电池组等)。
  • 输出电压范围:0.808V ~ 15V(可调),参考电压为 0.808V,支持外部分压设定。
  • 输出电流:最高 4A,适合供给中高功率负载。
  • 开关频率:500kHz,平衡体积与效率,可使用较小体积的电感与电容。
  • 同步整流:内置同步 MOSFET,降低整流损耗,提高轻载至中载效率。
  • 静态电流:700µA(Iq),有利于轻载与待机功耗控制。
  • 工作温度范围:-40℃ ~ +85℃(TA),满足工业级环境需求。
  • 封装:SOP-8-EP,带散热焊盘(EP)便于热管理与 PCB 散热。
  • 内置开关管,无需外接功率 MOSFET,简化方案设计。

二、典型特性与保护

RT8288AZSP 结合同步整流与 500kHz 开关频率,在中高输入电压下仍可维持良好转换效率。芯片通常集成常见保护功能,如欠压锁定(UVLO)、过流/电流限制、过温保护与过压保护等(具体保护行为请参照器件资料)。软启动与环路补偿设计可避免启动冲击与振荡,提高系统稳定性。

三、应用场景

  • 工业控制与自动化设备的集中/点对点电源。
  • 通信设备与基站模块的局部稳压。
  • 车载电子(非直接指定车规等级前提下,适用于 12V/24V 总线供电的附件电源)。
  • 医疗、安防、网络设备的供电模块。
  • 笔记本/便携设备的外设电源(需结合热与 EMC 设计)。

四、设计建议与注意事项

  • 输入侧需配置低 ESR 的去耦电容与足够的电容容量以抑制瞬态电流与开关尖峰;并靠近芯片输入引脚布局。
  • 输出电感需选型能承受 4A 连续电流且具较低直流阻抗(DCR),避免饱和。
  • 输出侧应使用低 ESR/低 ESL 电容以获得良好负载瞬态响应与稳定性。
  • PCB 布局应尽量缩短高电流回路(开关节点、输入电容、功率地)的路径,地平面完整;热焊盘(EP)必须焊接于 PCB 大面积散热铜箔以利散热。
  • 反馈网络布线要远离噪声较大的开关节点,保持反馈精度。
  • 根据负载特性调整环路补偿与软启动时间,确保系统在过载与短路情况下能可靠触发保护。

五、封装与采购信息

  • 封装形式:SOP-8-EP(外露散热焊盘)。
  • 品牌:RICHTEK(台湾立锜)。
  • 型号:RT8288AZSP。
    建议在正式设计前参考芯片完整规格书(Datasheet)以获取引脚定义、典型应用电路、完整电气特性与各项保护机制的详细参数。

总结:RT8288AZSP 是一款面向中高功率点对点应用的稳健降压型开关稳压器,凭借宽输入、可调输出与内置同步开关,能在体积、效率和热管理上为系统设计提供良好平衡。

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
