ETA1611S2G 产品概述
一、简介
ETA1611S2G 是钰泰（ETA）推出的一款升压型开关稳压器，单通道输出，内置开关管，工作电压范围宽（2.7V～6V），最高输出电流可达2A，开关频率为1MHz，静态工作电流仅250μA，适合对效率与尺寸有要求的便携类电源升压场合。工作温度范围：TA 下为 -40℃～+85℃，器件结温支持至 -40℃～+125℃。
二、主要规格要点
- 功能类型：升压型（Boost）
- 输入电压：2.7V～6V
- 最大输出电流：2A
- 开关频率：1MHz（固定）
- 同步整流：否（需外接肖特基二极管）
- 输出类型：可调（通过外部反馈分压设定）
- 静态电流 Iq：250μA
- 内置开关管，封装：SOT-23-6
三、特点与优势
- 高频率（1MHz）设计，外部电感、电容尺寸小，适合空间受限应用；
- 低静态电流，有利于电池供电设备待机续航；
- 内置开关管简化器件选型与布局，但采用非同步整流，外围需低压降肖特基二极管；
- SOT-23-6 小封装，便于批量贴片生产。
四、典型应用
- 移动电源与便携式设备升压；
- 手持测量仪器、传感器节点、电池供电的显示或驱动电路；
- 需要可调输出高压的小功率驱动场景（如单节电池升压至较高电压）。
五、应用与设计注意事项
- 二极管：由于非同步整流，应选用低正向压降、额定电流≥2A 的肖特基二极管以提高效率；
- 电感：1MHz 工作频率允许使用小体积电感，建议选用饱和电流高于峰值电流、DCR 低的电感，典型量级可在几μH 范围；
- 输出电容：建议采用低 ESR 的陶瓷电容（10–100μF 级），以降低纹波与增强稳定性；
- 热设计：SOT-23-6 封装散热有限，连续大电流工作时注意 PCB 散热，增加铜箔面积与过孔，避免器件过热；
- 布局：VIN、GND 与开关节点（SW）附近的输入电容、二极管、电感应尽量靠近 IC，反馈路径短且远离开关噪声源。
六、效率与可靠性提示
- 非同步架构在大电流条件下效率低于同步整流器件，合理选型二极管与电感、以及优化开关频率与输出电压，可获得较佳效率；
- 环境温度高时注意功率限流与热关断特性（参照器件数据手册），避免在高温下长时间满载工作。
七、总结
ETA1611S2G 以其宽输入电压、2A 输出能力与低静态电流，适合要求小体积、低静态损耗的电池供电升压场合。设计时应重视外部肖特基二极管、电感与 PCB 散热布局，以在保证稳定性的同时获得较高的实际效率。欲获取更详细的引脚定义、外部元件推荐值及参考电路，请参考钰泰官方数据手册。

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.
