ETA1061S2G产品概述
一、产品简介
ETA1061S2G是钰泰(ETA)推出的一款升压型开关稳压器，采用升压拓扑、内置开关管并支持同步整流，封装为SOT23-6。工作电压范围宽（550mV~5V），静态电流极低（Iq≈1μA），输出可调且单路输出，最大输出电流可达1A，适合对能耗敏感的便携与电池供电系统。
二、主要特性
- 输入电压：0.55V ～ 5V，支持极低电压启动/工作
- 输出类型：可调，方便适配不同负载需求
- 开关频率：1.076MHz ～ 1.4MHz，高频工作利于使用小体积电感与电容
- 同步整流：支持，提升轻载与中等负载下转换效率
- 静态电流：约1μA，适合长待机应用
- 最大输出电流：1A（实际可用电流受输入电压、升压比和热限影响）
- 工作温度：-40℃ ～ +85℃；封装：SOT23-6，便于小尺寸PCB设计
三、典型应用场景
- 1节或2节干电池/锂电池升压供电（低电压启动至5V以内）
- 便携式仪器、可穿戴设备、无线传感器节点
- 后备电源与功率受限的传感模块
- 需低静态电流和较高输出电流的嵌入式系统
四、设计与布局建议
- 高频开关利于减小被动元件，但需选择低直流电阻与合适饱和电流的电感，确保峰值电流能力。
- 输出电容建议使用低ESR陶瓷电容以减小输出纹波并提升瞬态响应。
- PCB走线要尽量缩短开关节点环路（开关管、二极管/同步MOS、输入电容），减小EMI和热阻。
- 调节输出时注意反馈分压阻值选择，防止噪声耦合影响稳压精度。
- 在高输出电流工作点注意热设计，SOT23-6需考虑铜箔散热和散热路径。
五、选型与注意事项
在实际设计前，请参考ETA1061S2G完整数据手册确认引脚定义、过流/过温保护阈值、启动特性及效率曲线等关键参数。由于最大输出1A与效率受输入电压和转换比影响，建议在目标工况下进行仿真与实测验证，以确定电感、MOS负载能力和散热方案。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
