<p><em>器件符合PMBus 1.3电源系统管理标准，简化POL转换器设计</em></p>
<p><span>日前</span><span>，Vishay Intertechnology, Inc.（NYSE 股市代号：VSH）</span><span>推出新型</span><span>15 A</span><span>、</span><span>25 A</span><span>和</span><span><span> </span>40 A</span><span>系列器件</span><span>-</span><span>--</span><a href="http://www.vishay.com/ppg?77863"><span>SiC45x系列</span></a><span>，</span><span>扩充其</span><span>microBUCK</span><span>®</span><span><span> </span></span><span>同步降压稳压器，新型器件采用热增强</span><span>5 mm<span> </span></span><span>x</span><span><span> </span>7 mm PowerPAK</span><span>®</span><span><span> </span>MLP34-57</span><span>封装，</span><span>输入电压为4.5 V</span><span>~</span><span><span> </span>20 V</span><span>。Vishay Siliconix<span> </span></span><a href="http://www.vishay.com/ppg?77863"><span>SiC45x系列</span></a><span>稳压器符合PMBus 1.3电源系统管理标准，功率密度和瞬变响应能力优于前代稳压器。</span></p>
<p><span><span>日前发布的器件在小型封装内含有高性能</span></span><span><span>n</span></span><span><span>沟道沟槽式MOSFET和</span></span><span><span>PWM</span></span><span><span>控制器，提高了功率密度。稳压器静态</span></span><span><span>工作电流低，峰值效率达</span></span><span><span>98 %，减少</span></span><span><span>功率损耗。这款集成式器件有助于简化高性能负载点</span></span><span><span>（</span></span><span><span>POL</span></span><span><span>）</span></span><span><span>转换器设计，减少配置环路补偿的外部元器件数量。</span></span></p>
<p><span><span>SiC45x</span></span><span><span>系列稳压器</span></span><span><span>在整个</span></span><span><span>V</span></span><span><span>IN</span></span><span><span><span> </span></span></span><span><span>和</span></span><span><span>V</span></span><span><span>OUT</span></span><span><span>工作电压范围内具有内部补偿功能。器件具有高度配置能力，输入电压范围宽，输出电压在</span></span><span><span>0.3 V</span></span><span><span><span> </span></span></span><span><span>~12 V范围内可调。稳压器用途广泛，适合各种应用，包括云计算、企业服务器和工业计算机的</span></span><span><span>POL</span></span><span><span>转换器，以及网络、通信和存储系统。</span></span></p>
<p><span>所有</span><span>SiC45x</span><span>系列器件占位兼容，便于设计者扩展解决方案，从而优化性价比，同时加快设计速度。稳压器开关频率可在</span><span>300<span> </span></span><span>kHz~</span><span>1.5<span> </span></span><span>MHz范围内调节，具有强制连续工作、节能或超声波三种工作模式。</span></p>
<p><span>稳压器恒定导通时间</span><span>（</span><span>COT</span><span>）</span><span>架构具有超快瞬变响应能力，只需要很小的输出电容，可在宽负载范围内严格调节纹波。同时，无论使用哪种类型的输出电容器，稳压器都能保持环路稳定性。器件集成的各种可靠保护监测功能保证稳定运行，包括输出过压和欠压保护</span><span>（</span><span>OVP / UVP</span><span>）</span><span>、逐脉冲过流保护</span><span>（</span><span>OCP</span><span>）</span><span>、差分远端输出检测，以及迟滞过热保护</span><span>（</span><span>OTP</span><span>）</span><span>。</span></p>
<p><span>SiC45X</span><span>系列现可提供样品并已实现量产，供货周期为16周。</span></p>
