ETA3415S6G 产品概述

一、产品简介

ETA3415S6G 是钰泰(ETA)推出的一款降压型(Buck)同步整流开关稳压器,集成高侧与低侧开关管,单输出通道,工作电压范围宽(2.6V–6.5V),输出可调(0.6V–6.5V),最大输出电流可达1A。工作频率为3MHz,封装为超小型 SOT563,适合空间受限与对外围元件尺寸有严格要求的便携与嵌入式应用。

二、主要规格

  • 功能类型:降压(同步整流)
  • 输入电压:2.6V ~ 6.5V
  • 输出电压:可调 0.6V ~ 6.5V(通过外部分压电阻设定)
  • 输出电流:最高 1A(需关注热限与电流限制)
  • 开关频率:3MHz(固定)
  • 工作温度:-40℃ ~ +85℃
  • 开关管:内置(集成高/低端MOSFET)
  • 输出通道:单通道
  • 封装:SOT563
  • 品牌:ETA(钰泰)

三、器件特点与优势

  • 同步整流结构提高轻载与重载效率,减少外部肖特基二极管需求;
  • 3MHz 高频率使外部电感与电容尺寸大幅减小,利于超小型电源模组设计;
  • 宽输入与输出电压范围,支持多种电池与系统电压方案;
  • 内置开关器件简化PCB布局与BOM,降低整体成本;
  • SOT563 小封装适合空间受限的便携终端与物联网终端。

四、典型应用场景

  • 移动设备与可穿戴设备的点位电源;
  • 电池供电的传感器与物联网节点;
  • 单板机与MCU核心电源(1A 以下负载);
  • 工业控制、通信设备的局部电源模块。

五、参考设计与外围元件建议

  • 电感:建议选择低DCR、饱和电流高于1A的功率电感,典型值依据输出电压与允许电流纹波选择(3MHz 高频允许使用 0.22µH ~ 1.0µH 范围的贴片电感);
  • 输入/输出电容:优先使用 X5R/X7R 陶瓷电容,输入侧配合去耦电容(例如 4.7µF~10µF)并靠近 VIN 引脚放置;输出侧使用低ESR 的陶瓷电容以保证环路稳定与低输出纹波;
  • 反馈网络:通过两只高阻值分压电阻设置输出电压,注意热漂与容差;
  • 其他:由于器件为同步拓扑,无需外部整流二极管,但建议在系统设计中考虑输入浪涌保护与滤波。

六、PCB布局与热管理建议

  • 高频工作要求最短且最宽的输入回路与开关回路走线,尽量将输入电容靠近 VIN 和 GND 引脚放置;
  • 将电感置于 IC 输出端侧,减小开关节点环路面积;
  • 在 SOT563 下方或周围布置过孔(via)连接内层或底层散热铜箔,提升热传导能力;
  • 在高功耗或高环境温度下,需对输出电流进行适当降额,避免热关断。

七、可靠性与使用建议

  • 工作时确保 VIN 始终位于 2.6V~6.5V 范围;启动、关断顺序应考虑系统整体设计以避免瞬态异常;
  • 在高温或高负载场景中进行实际功率热仿真与测试,确认 PCB 散热措施;
  • 对于关键应用,建议在样片阶段进行负载、纹波、瞬态响应与长时稳定性测试。

更多详细参数、引脚定义与典型应用电路可参考钰泰官方 ETA3415S6G 数据手册与参考设计资料。若需针对具体应用的参数优化或参考电路图,可提供输入/输出电压、最大负载与版图限制,以便给出更精确的选型与布局建议。

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
