H8116A30NR升压型DC-DC电源芯片产品概述

H8116A30NR是上海矽朋(Siproin)推出的一款升压型固定输出DC-DC电源芯片,专为低功耗、小体积电池供电场景设计,集成同步整流与内置开关管,兼顾效率与便携性,适用于宽温环境下的各类便携及IoT设备。

一、产品核心定位与设计亮点

H8116A30NR聚焦电池供电设备的低功耗+小体积需求,核心设计亮点包括:

  1. 宽输入电压覆盖:2.1V5.5V范围,适配单节锂电池(2.04.2V)、2节干电池(3.0V)等常见供电源;
  2. 超低待机功耗:仅15μA静态电流,大幅延长电池待机时间(100mAh电池待机超70天);
  3. 高效同步整流:内置NMOS上下管,替代续流二极管,轻载效率提升5%~10%;
  4. 内置功率管:无需外置开关管,简化外围电路,缩小PCB面积;
  5. 固定精准输出:3V输出精度±1%,适配MCU、传感器等3V负载;
  6. 工业级温宽:-40℃~+85℃,满足户外、车载等复杂环境需求。

二、关键电气参数与应用匹配性

1. 输入电压范围(2.1V~5.5V)

支持单节锂电池放电截止状态(2.1V)仍稳定工作,同时覆盖2节AA/AAA干电池(3.0V)、USB 5V(宽范围兼容),无需额外升压/降压转换,简化系统设计。

2. 静态电流(Iq=15μA)

待机模式下仅消耗15μA电流,是同类异步整流芯片的1/3~1/5,适合长期低功耗待机的IoT节点、智能手环等设备。

3. 开关频率(300kHz)

采用固定300kHz频率,平衡效率与元件体积:电感可选用10μH小封装(如SOT-23),电容用1μF~10μF陶瓷电容,无需 bulky 元件,适配便携设备高密度布局。

4. 同步整流效率

内置NMOS下管替代续流二极管,导通压降从0.3~0.7V降至0.1V以下:

  • 轻载(10mA输出)效率≥80%;
  • 满载(100mA输出)效率≥85%,比异步方案提升显著。

三、拓扑结构与工作原理

H8116A30NR采用升压(Boost)拓扑,核心工作流程:

  1. 充电阶段:内置NMOS上管导通,下管截止,输入电压给电感充电,储存磁能;
  2. 放电阶段:上管截止,下管导通(同步整流),电感通过下管向输出电容/负载放电,输出电压高于输入;
  3. 反馈调节:内置反馈电路检测输出电压,动态调整开关占空比,稳定3V输出。

同步整流的核心优势是降低导通损耗,尤其在低电流场景下,避免续流二极管的压降浪费,提升电池续航。

四、封装与典型应用场景

1. 封装形式

SOT-23(5引脚)封装,尺寸仅2.9mm×2.5mm×1.1mm,适合便携设备的小面积PCB设计,可兼容自动贴装工艺。

2. 典型应用

  • 便携电子:蓝牙音箱、智能手环、TWS耳机(单节锂电池供电);
  • 低功耗IoT:无线传感器节点、智能门锁(待机模式)、远程监控摄像头;
  • 干电池产品:电视遥控器、电子玩具、小型LED手电筒;
  • 工业场景:户外环境监测传感器、车载小电器(宽温适配)。

五、环境适应性与可靠性

  • 宽温工作:-40℃~+85℃工业级温宽,可在低温(北方冬季户外)、高温(车内夏季)下稳定运行;
  • 内置保护:常规电源芯片级保护(过流OCP、过温OTP),防止负载短路或芯片过热损坏;
  • 抗干扰设计:300kHz开关频率避开AM广播等噪声频段,内置EMI优化电路,降低对周边敏感元件的干扰。

总结

H8116A30NR凭借宽输入、低功耗、高效率、小体积四大核心优势,成为电池供电便携设备、低功耗IoT设备的理想升压电源方案,尤其适合对待机时间、体积有严格要求的场景。

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
