SSP8711升压型DC-DC转换器产品概述

SSP8711是上海矽朋(Siproin)推出的一款升压式(Boost)DC-DC转换器,主打宽电压范围、低静态功耗与小型化设计,适配电池供电、工业控制等多场景需求,以下从核心特性、参数、封装及应用等维度展开说明。

一、核心功能与拓扑结构

SSP8711采用经典升压拓扑结构,核心功能是将低于目标输出的输入电压提升至所需电平——例如,可将2V输入(如单节镍氢电池)升压至5V,或把12V车载电源升压至24V,满足后级电路(如MCU、传感器、显示模块)的供电需求。拓扑结构的选择决定了其“输入电压≤输出电压”的工作逻辑,且内置开关管的设计简化了外部元件搭配,无需额外外置MOS管即可实现升压转换。

二、关键电气参数解析

SSP8711的参数设计围绕“宽适应、低功耗、小型化”三个核心,具体表现为:

2.1 宽电压输入输出范围

  • 输入电压:2V~24V,覆盖常见电池(2节干电池3V、单节锂电池3.7V、12V/24V铅酸电池)及车载电源波动范围;
  • 输出电压:2.5V~24V(可调),通过外部电阻分压即可设置目标电压,适配5V(USB供电)、9V(工业模块)、12V(显示驱动)等多种需求。

2.2 高开关频率与小型化适配

开关频率固定为1.2MHz,高于多数同类产品的500kHz以下水平。高频率带来两个关键优势:① 电感可选用10μH22μH的小型化贴片电感(如CDRH3D16系列),电容可搭配1μF4.7μF陶瓷电容,显著缩小电路占板面积;② 输出纹波更小(典型值<50mV),适合对电源噪声敏感的模拟电路(如传感器信号调理)。

2.3 低静态电流与长待机

静态电流(Iq)仅100μA,远低于同类产品的200μA以上水平。这意味着设备待机时(无负载或轻负载),电池消耗极低——例如,用100mAh锂电池供电,仅静态电流的待机时间可达约1100小时,非常适合物联网传感器、智能穿戴等低功耗场景。

2.4 宽温工作范围

工作温度覆盖**-40℃~+80℃(环境温度TA)**,达到工业级温度标准,可适应户外低温(如北方冬季)、车间高温(如设备散热环境)等复杂工况,无需额外散热设计即可稳定运行。

三、封装与集成特性

SSP8711采用SOT23-6封装,尺寸仅为2.9mm×2.6mm×1.1mm,属于小型化贴片封装,可直接贴装在高密度PCB上,适配智能手环、蓝牙耳机等紧凑设备的空间限制。

此外,产品内置N沟道功率开关管,无需外置MOS管,仅需搭配电感、电容、分压电阻即可完成电路设计,外部元件数量不超过5个,显著降低BOM成本与设计复杂度,缩短产品开发周期。

四、典型应用场景

结合参数特性,SSP8711的核心应用场景包括:

  1. 便携电子设备:智能手环(将3.7V锂电池升压至5V给充电模块)、蓝牙耳机(升压至3.3V驱动音频芯片);
  2. 物联网终端:环境传感器节点(电池供电,低静态电流延长待机)、智能门锁(升压至6V驱动电机);
  3. 工业控制模块:PLC辅助供电(12V输入升压至24V)、传感器信号调理电路;
  4. 车载小设备:车载蓝牙适配器(12V输入升压至5V)、胎压监测传感器(3.7V锂电池升压至3.3V)。

五、产品优势总结

SSP8711的核心竞争力体现在:

  • 宽电压适配:覆盖从2V到24V的输入输出范围,兼容多类电源与负载;
  • 低功耗长待机:100μA静态电流,适合电池供电场景的长待机需求;
  • 小型化设计:1.2MHz频率+SOT23-6封装,缩小电路体积,适配紧凑设备;
  • 简化设计:内置开关管,外部元件少,降低开发成本与设计难度;
  • 宽温可靠:工业级温度范围,适应户外、工业等复杂工况。

作为上海矽朋推出的升压型DC-DC转换器,SSP8711在便携、物联网、工业等领域具有较强的实用性,可满足多数升压供电需求。

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.
