LP87561-Q1 具有集成开关的四相 16A 降压转换器

<h2>描述</h2> LP8756x-Q1器件专为满足各种汽车电源应用中最新处理器和平台的电源管理要求而设计。该器件包含四个降压直流/直流转换器内核，这些内核可配置为1个四相输出，1个三相和1个单相输出，2个两相输出，1个两相和2个单相输出，或者4个单相输出。该器件由I 2 C兼容串行接口和使能信号进行控制。 自动脉宽调制（PWM）到脉频调制（PFM）操作（ AUTO模式）与自动增相和切相相结合，可在较宽输出电流范围内最大限度地提高效率.LP8756x-Q1支持对多相位输出的远程差分电压检测，可补偿稳压器输出与负载点（POL）之间的IR压降，从而提高输出电压的精度。此外，可以强制开关时钟进入PWM模式以及将其与外部时钟同步，从而最大限度地降低干扰。 LP8756x- Q1器件支持在不添加外部电流检测电阻器的情况下进行负载电这个序列可能包括用于控制外部稳压器，负载开关和处理器复位的GPIO信号。在启动和电压变化期间，该器件会对输出压摆率进行控制，从而最大限度地减小输出电压过冲和浪涌电流。 <h2>特性</h2> <ul> <li>符合汽车类标准</li> <li>具有符合AEC-Q100标准的下列特性：<ul> <li>器件温度1级：-40℃至+ 125℃的环境运行温度范围</li> <li>器件HBM ESD分类等级2 </li> <li>器件CDM ESD分类等级C4B </li> </ul> < /li> <li>输入电压：2.8V至5.5V </li> <li>输出电压：0.6V至3.36V </li> <li>四个高效降压直流/直流转换器内核：<ul > <li>最大输出电流：16A（4A /相）</li> <li>可编程输出电压压摆率范围：0.5mV /μs至10mV /μs</li> </ul> </li> <li>开关频率：2MHz </li> <li>扩频模式和相位交错</li> <li>可配置通用I /O（GPIO）</li> <li> I 2 C兼容接口，支持标准（100kHz），快速（400kHz），快速+（1MHz）和高速（3.4MHz）模式</li> <li>具有可编程屏蔽的中断功能</li> <li>可编程电源正常信号（PGOOD）</li> <li>输出短路和过载保护</li> <li>过热警告和保护</li> <li>过压保护（OVP）和欠压锁定（UVLO ）</li> </ul> 所有商标均为各自所有者的财产。 <h2>参数与其它产品相比多通道IC（PMIC） </h2> Regulated outputs (#) Processor supplier Processor name Vin (Min) (V) Vin (Max) (V) Step-Up DC/DC Controller Step-Down DC/DC Controller LDO Step-Up DC/DC Converter Step-Down DC/DC Converter Iout (Max) (A) Iq (Typ) (mA) Features Shutdown Current (Typ) (uA) Rating Operating temperature range (C) Configurability Package Group Package size: mm2:W x L (PKG) LP87561-Q1 LP873220-Q1 LP87332A-Q1 LP87524B-Q1 LP87524J-Q1 LP87564-Q1 LP87565-Q1 LP875701-Q1 LP87702-Q1 4 4 4 4 4 2 1 3 Texas Instruments TI Texas Instruments Texas Instruments Texas Instruments Mobileye TI DRA71x DRA79x TDA3x AWR1243 AWR1243, AWR1443 Jacinto 6+, TDA2+ EyeQ4 Mid AWRxxx, IWRxxx 2.8 2.8 2.8 2.8 2.8 2.8 2.8 2.8 2.8 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 2 0 0 0 0 0 0 0 0 0 0 0 0 1 2 2 4 4 4 2 1 2 16 2 3 4 4 4 16 10 3.5 0.0067 0.0067 0.0067 27 Dynamic Voltage Scaling Enable Enable Pin I2C Control Over Current Protection Power Good Power Sequencing Power Supply and System Monitoring Spread-Spectrum Clock (SSC) Generation Synchronous Rectification Thermal Shutdown UVLO Fixed Enable Pin I2C Control Power Good Power Sequencing Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Adjustable Enable Pin I2C Control Power Good Power Sequencing Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Adjustable Diagnostics Dynamic Voltage Scaling Enable I2C Control Over Current Protection Power Good Power Sequencing Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Fixed Diagnostics Dynamic Voltage Scaling Enable Enable Pin I2C Control Over Current Protection Power Good Power Sequencing Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Fixed Diagnostics Dynamic Voltage Scaling Enable Enable Pin I2C Control Over Current Protection Power Good Power Sequencing Power Supply and System Monitoring Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Fixed Diagnostics Dynamic Voltage Scaling Eco-mode Enable Enable Pin I2C Control Over Current Protection Power Good Power Sequencing Power Supply and System Monitoring Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Fixed Dynamic Voltage Scaling Enable Enable Pin I2C Control Over Current Protection Power Good Power Sequencing Power Supply and System Monitoring Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Fixed Dynamic Voltage Scaling Enable Enable Pin I2C Control Over Current Protection Power Good Power Sequencing Power Supply and System Monitoring Spread-Spectrum Clock (SSC) Generation Thermal Shutdown UVLO Fixed 1.4 1.4 1.4 1 Automotive Automotive Automotive Automotive Automotive Automotive Automotive Automotive Automotive -40 to 125 -40 to 125 -40 to 125 -40 to 125 -40 to 125 -40 to 125 -40 to 125 -40 to 125 -40 to 125 Factory programmable Software configurable Factory programmable Software configurable Factory programmable Software configurable Factory programmable Software configurable Factory programmable Software configurable Factory programmable Software configurable VQFN-HR | 26 VQFN | 28 VQFN | 28 VQFN-HR | 26 VQFN-HR | 26 VQFN-HR | 26 VQFN-HR | 26 VQFN-HR | 26 VQFN | 32 26VQFN-HR: 18 mm2: 4 x 4.5 (VQFN-HR | 26) 28VQFN: 25 mm2: 5 x 5 (VQFN | 28) 28VQFN: 25 mm2: 5 x 5 (VQFN | 28) 26VQFN-HR: 18 mm2: 4 x 4.5 (VQFN-HR | 26) 26VQFN-HR: 18 mm2: 4 x 4.5 (VQFN-HR | 26) 26VQFN-HR: 18 mm2: 4 x 4.5 (VQFN-HR | 26) 26VQFN-HR: 18 mm2: 4 x 4.5 (VQFN-HR | 26) 26VQFN-HR: 18 mm2: 4 x 4.5 (VQFN-HR | 26) 32VQFN: 25 mm2: 5 x 5 (VQFN | 32) 无样片无样片 <input type="hidden" value="1" id="maxLength" /> <h2>方框图</h2> <ul id="items" class="items"> <li class="list21" id="list21"> <figure class="ti_imagearea"> <svg role="img"><use xlink:href="/etc/designs/ti/images/icons/svg/ti_icons-actions.svg#zoom-in"></use></svg> <img src="http://file.elecfans.com/web1/M00/81/4F/o4YBAFwvPIWAcHAKAABfZOiYEZM166.gif"> </figure> LP87561-Q1 - 功能方框图 </li> </ul>
