ETA1061D2G升压型DC-DC转换器产品概述

一、核心功能与特性

ETA1061D2G是钰泰半导体针对低功耗电池供电场景设计的同步升压型DC-DC转换器,核心特性聚焦小型化、高效率与长续航,具体包括:

  1. 内置同步整流:无需外部肖特基二极管,转换效率提升5%~8%(典型值92%),简化BOM成本;
  2. 超宽输入覆盖:550mV~5V输入范围,兼容纽扣电池(CR2032)、干电池(AA/AAA)、锂电池(3.7V)等多类电源;
  3. 极低静态电流:仅1μA(典型值),待机功耗较传统升压芯片降低90%以上,显著延长电池续航;
  4. 高输出能力:1A连续输出/1.5A峰值,满足蓝牙模块、小型显示屏等主流小功率负载需求;
  5. 高频设计:1.076MHz~1.4MHz开关频率,支持1μH小电感与微型电容,大幅节省PCB空间;
  6. 可调输出电压:通过外部电阻分压灵活设置(2V~5.5V),适配不同负载电压需求;
  7. 内置功率开关:无需外部MOSFET,进一步简化电路设计。

二、关键参数深度解析

ETA1061D2G的参数设计精准匹配低功耗场景痛点,核心参数亮点如下:

  • 输入电压:550mV~5V——纽扣电池放电至550mV仍可稳定工作,覆盖从低电量到满电的全生命周期;
  • 静态电流(Iq):1μA——适合长期待机的IoT传感器、电子标签等产品,待机电流远低于行业平均水平;
  • 输出电流:1A连续——满足蓝牙5.0模块(最大500mA)、小型LCD屏(300mA)等负载,无需并联额外芯片;
  • 开关频率:1.076MHz1.4MHz——高于AM频段(535kHz1.7MHz),避免射频干扰,同时小电感(1μH)可实现高效转换;
  • 工作温度:-40℃~+85℃(TA)——工业级温度范围,适应户外(智能农业传感器)、车载(小型蓝牙设备)等恶劣环境;
  • 同步整流效率:92%(VIN=3V,VOUT=5V,IOUT=500mA)——比异步整流方案效率提升,减少发热与电池损耗。

三、封装与可靠性设计

ETA1061D2G采用DFN-6(2×2mm)封装,兼具小型化与可靠性:

  1. 超小尺寸:2×2mm封装仅占4mm²PCB面积,适配可穿戴(智能手环)、IoT终端(传感器节点)等微型产品;
  2. 高效散热:DFN焊盘直接散热,比SOT-23封装散热效率提升30%,1A连续输出时无明显温升;
  3. 抗干扰与保护:内置ESD防护(2kV HBM)、软启动(1ms)、过流保护(OCP)、过温保护(OTP),提升系统稳定性;
  4. 工艺兼容性:支持常规回流焊,无需特殊SMT工艺,降低生产门槛。

四、典型应用场景

ETA1061D2G的特性使其广泛适配以下低功耗场景:

  1. 可穿戴设备:智能手环(3.3V/5V输出+低待机)、智能手表(小封装+高输出)、健康监测仪(血氧/体温计);
  2. IoT终端:无线传感器节点(温湿度/光照,长期待机)、智能门锁(宽输入+低功耗)、电子标签(纽扣电池供电);
  3. 便携式电子:蓝牙耳机充电盒(3.7V升压至5V)、迷你蓝牙音箱(1A输出)、小型移动电源(低待机);
  4. 工业低功耗设备:小型工业传感器(-40℃~+85℃)、智能农业监测节点(户外环境)。

五、设计适配性优势

ETA1061D2G在开发端具有显著适配性:

  1. BOM极简:仅需1电感、2电容、2分压电阻(含芯片共5个元件),成本较同类方案降低15%;
  2. 输出灵活:通过R1/R2分压实现VOUT=1.2V×(1+R1/R2),覆盖2V~5.5V常见输出;
  3. 抗干扰性:高频开关避开AM频段,软启动避免上电浪涌,适合射频敏感场景;
  4. 宽电源兼容:无需额外电源切换电路,适配纽扣电池、干电池、锂电池等多类电源。

ETA1061D2G通过平衡效率、尺寸、成本与可靠性,成为低功耗电池供电场景的优选升压方案,尤其适合可穿戴、IoT终端等小型化产品的快速开发。

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
