SM8002AAX 产品概述

一、产品概述

SM8002AAX 是硅力杰(silergy)推出的一款高集成度降压型同步开关稳压器,采用 SOT23-5 小封装,内置功率开关,支持可调输出(0.6V5.5V)。工作电压范围为 2.5V5.5V,最大输出电流可达 2A,开关频率 1.5MHz,静态电流仅 50µA,适合空间受限且对待机功耗有严格要求的电源设计。

二、主要性能参数

  • 功能类型:降压(Buck)
  • 输入电压:2.5V ~ 5.5V
  • 输出电压:0.6V ~ 5.5V(可调)
  • 输出电流:最高 2A
  • 开关频率:1.5MHz
  • 静态电流(Iq):50µA
  • 同步整流:内置(有源整流)
  • 封装:SOT23-5
  • 工作温度:-40℃ ~ +85℃
  • 保护与特性:轻载高效模式、逐波限流、过流保护、输出放电、打嗝限流

三、典型应用场景

  • 电池供电的便携设备与可穿戴终端
  • IoT 节点、无线模块与传感器供电
  • 移动电源、便携媒体播放器、便携式摄像设备
  • 工业与消费类设备的点对点电源模块

四、产品优势与设计要点

  • 高集成度与 1.5MHz 高频率,可大幅减小电感和输出电容体积,利于小型化设计。
  • 低静态电流和轻载高效模式,在待机或轻载条件下保持高效率,延长电池续航。
  • 多重保护机制(逐波限流、打嗽限流、过流保护)提升系统可靠性,输出放电功能可加速系统掉电。
  • 设计建议:输入电容靠近 VIN 与 GND,开关路径(SW、电感、输出电容)走线尽量短且宽;为 SOT23-5 封装提供充足的 PCB 散热铜箔;选型时电感和电容需满足峰值电流与低 ESR 要求以保证稳定性与效率。

五、总结

SM8002AAX 以其小体积、高效率、丰富的保护功能和超低静态电流,适合对空间和功耗敏感的便携及嵌入式电源方案。做产品化设计时,按推荐的布局与外设元件选择可获得最佳性能与可靠性。

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
