<p><strong>【</strong><strong>2020<span> </span></strong><strong>年</strong><strong><span> </span></strong><strong>12</strong><strong><span> </span></strong><strong>月</strong><strong><span> </span></strong><strong>15</strong><strong><span> </span></strong><strong>日美国德州普拉诺讯】</strong><span>Diodes<span> </span></span><span>公司</span><span><span> </span>(Nasdaq:DIOD)<span> </span></span><span>宣布推出两款高集成度的同步降压转换器，透过电源稳定</span><span><span> </span>(Power Good)<span> </span></span><span>输出及为噪音敏感产品应用而开发的创新</span><span><span> </span>EMI<span> </span></span><span>减缓噪音技术，简化汽车电源系统的电路设计。</span></p>
<p><a href="https://www.diodes.com/part/AP63356Q"><span>AP63356Q</span></a><span><s… href="https://www.diodes.com/part/AP63357Q"><span>AP63357Q</span></a><span><s…，输入电压范围为</span><span><span> </span>3.8V<span> </span></span><span>至</span><span><span> </span>32V<span> </span></span><span>间。利用峰值电流控制模式及高端与低端电源的晶载金属氧化物半导体场效晶体管</span><span><span> </span>(MOSFET)</span><span>，降压转换器将所需的外部零件降至最低，以减少材料清单</span><span><span> </span>(BOM)<span> </span></span><span>成本及电路板体积。</span></p>
<p><span>以上两产品皆配有电源稳定指标，内含</span><span><span> </span>5MΩ<span> </span></span><span>上拉电阻，有助电源排序。为更有效帮助电源排序，降压转换器的使能引脚具精确的临界电压，可调整输入电压装置与欠压锁定</span><span><span> </span>(UVLO)</span><span>。使能引脚可承受高电压，因此能直接连接</span><span><span> </span>VIN</span><span>，以简化装置自动启动程序。关闭时，降压转换器的关闭电流只有</span><span><span> </span>0.6µA</span><span>。</span></p>
<p><span>该产品专有的闸极驱动器可确保切换顺畅度，同时避免节点交换时产生振铃，将高频辐射噪音降至最低。扩频</span><span><span> </span>(FSS)<span> </span></span><span>能分散切换时产生的噪音，让产品能安静运作。</span></p>
<p><span>AP63356Q<span> </span></span><span>在所有负载切换频率为</span><span><span> </span>450kHz<span> </span></span><span>时，以</span><span><span> </span>PWM<span> </span></span><span>模式持续运作。在轻负载时，</span><span>AP63357Q<span> </span></span><span>将转为</span><span><span> </span>PFM<span> </span></span><span>模式，在负载为</span><span><span> </span>5mA<span> </span></span><span>时，以高达</span><span><span> </span>86%<span> </span></span><span>的效率运作，空载的静态电流仅为</span><span><span> </span>22µA</span><span>。</span></p>
<p><span>两者皆具有低损耗型线性稳压器，意即在输入电压降至接近输出电压时，可保持输出电压调整率。内建保护功能包含低电压保护</span><span><span> </span>(UVP)</span><span>、逐周期峰值电流限制以及热关机。这两项产品因上述保护功能以及</span><span><span> </span>40V (400ms)<span> </span></span><span>输入电压突波承受能力，可提供强大的汽车</span><span><span> </span>POL<span> </span></span><span>解决方案。</span></p>
