ETA1061V50S2G升压型DC-DC转换器产品概述

一、核心功能与拓扑设计

ETA1061V50S2G是钰泰(ETA)针对电池供电场景优化的升压型固定输出DC-DC转换器,采用经典Boost升压拓扑结构,核心功能是将低输入电压高效转换为稳定的5V输出。其内置同步整流电路与功率开关管,无需外部续流二极管或功率MOSFET,单输出通道设计满足单负载稳定供电需求,简化外围电路的同时提升了设计可靠性。

二、关键电气参数与性能解析

该器件的参数覆盖了超低压启动、高负载能力、低待机功耗等电池供电设备的核心需求,具体如下:

  • 宽输入电压范围:550mV~5V,支持单节锂电池(放电后期可低至2V)、纽扣电池(如CR2032)甚至超低压启动,解决了电池深度放电时的供电断供问题;
  • 固定输出与负载能力:输出电压固定为5V,最大输出电流1A,可驱动蓝牙模块、小型MCU、传感器等常见负载;
  • 高频开关设计:1.4MHz开关频率,允许使用小尺寸电感(如10μH)和陶瓷电容,大幅节省PCB空间,适配可穿戴、IoT模块等小型化产品;
  • 超低静态电流:1.2μA(典型值),待机状态下几乎不消耗电池能量,显著延长电池续航时间(如纽扣电池供电设备可待机数月);
  • 内置开关管:无需外接功率器件,减少外部元件数量,降低设计复杂度与成本。

三、同步整流技术提升效率

ETA1061V50S2G采用内置同步整流方案,相比传统异步整流(依赖续流二极管),具有明显效率优势:

  • 重载效率:同步整流管的导通电阻远低于二极管正向压降,输出1A时转换效率可达90%以上;
  • 轻载优化:通过控制逻辑降低轻载下的开关损耗,即使负载电流低至10mA,效率仍保持在80%以上;
  • 全负载平衡:同步整流配合低静态电流,实现“待机超低功耗+全负载高效”的平衡,适配设备从待机到工作的多样化状态。

四、封装与环境适应性

  • 小尺寸封装:采用SOT23-6封装,尺寸仅2.9mm×1.6mm×1.1mm,适合对空间要求严格的产品(如智能手环、蓝牙信标);
  • 宽温工作范围:-40℃~+85℃工业级温度范围,可适应户外环境(如温度波动大的传感器节点)、工业现场等 harsh 场景,可靠性高。

五、典型应用场景

ETA1061V50S2G的参数特性使其广泛适用于以下场景:

  1. 低功耗IoT终端:温湿度传感器、烟雾报警器、蓝牙信标等,超低压启动+低静态电流满足长期待机需求;
  2. 可穿戴电子:智能手环、智能手表、TWS耳机充电盒等,小封装适配小型化设计,5V输出驱动无线模块;
  3. 电池供电小型设备:便携应急灯、小型移动电源(低容量)、电子标签等,宽输入范围适配不同电池类型;
  4. 工业传感器节点:工业现场的温度、压力传感器,宽温范围保证恶劣环境下的稳定工作。

该器件通过高效升压、低功耗、小封装等特性,为电池供电类设备提供了高性价比的升压解决方案,适合对空间、续航要求较高的电子设计。

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
