<p><span>安森美半导体延续</span><span>其</span><span>在电源管理和USB-C PD方案的领先地位</span><span>，终推出这</span><span>首款集成</span><span>的</span><span>同步整流器和自主控制器产品</span><span>，简化次级端</span><span>系统设计。FAN6390是安森美半导体</span><span>USB-C PD 3.0控制器系列</span><span>集成</span><span>PPS的</span><span>首</span><span>款</span><span>器件</span><span>。</span><span>安森美半导体</span><span>高级总监兼总经理Scott</span><span><span> </span></span><span>Haddow说</span><span>：“更</span><span>大容量电池</span><span>需</span><span>具备</span><span>相同或更快充电时间的趋势正在加速USB-C PD的采用。FAN6390</span><span>产品系列实现</span><span>的</span><span>集成度</span><span>令人</span><span>注目</span><span>，</span><span>将</span><span>增强</span><span>行</span><span>业设计并提高旅行适配器的功率密度</span><span>。”</span><span>优化的结构</span><span>提供基于状态机的</span><span>运行模式，实现</span><span>PD 3.0和PPS功能</span><span>所需</span><span>的所有功能，从而简化了最终产品的设计和制造。FAN6390领先</span><span>业界</span><span>的同步整流器FET驱动技术实现了高</span><span>能</span><span>效</span><span>。</span><span>FAN6390</span><span>的微调选项设置</span><span>还</span><span>为设计人员提供灵活性和可编程性。</span></p>
<p><span>内置高分辨率10位模数转换器</span><span>（</span><span>DAC</span><span>）</span><span><span> </span>完全符合USB-C PD 3.0要求，精细地解决了PPS恒流/恒压（CC / CV）要求</span><span>。</span><span>安森美半导体提供经</span><span>全面</span><span>验证的参考设计，进一步帮助设计人员简化集成</span><span>工作</span><span>。NCP12601变频控制器</span><span>添增</span><span>安森美半导体广泛的USB-C PD 3.0阵容，</span><span>它</span><span>结合多模式连续电流模式或非连续电流模式（CCM / DCM）与谷底开关，以适应各种负载条件。此方法比传统的固定频率脉宽调制</span><span>（</span><span>PWM</span><span>）</span><span>控制器</span><span>能效更高</span><span>。</span><span>添加谷底</span><span>锁定和专有的静音跳</span><span>周期特性显著提高噪声性能</span><span>到</span><span>领先</span><span>市场</span><span>的水平，而频率抖动则提供</span><span>改善的</span><span>电磁干扰</span><span>（</span><span>EMI</span><span>）</span><span>特征</span><span>。</span></p>
<p><span>要</span><span>符合</span><span>USB-C PD 3.0标准对设计人员可能是个挑战，NCP12601</span><span>含</span><span>独特的自动调谐和双级过流保护（OCP），</span><span>实现</span><span>所需的</span><span>OCP</span><span>功能</span><span>以</span><span>符合</span><span>该标准</span><span>要求</span><span>。</span><span>同时，低损耗的</span><span>V</span><span>CC</span><span>偏置可实现宽输出电压范围，而无需额外的外部电路或复杂的变压器设计。</span></p>
<p><span>可调过功率保护提供斜率补偿，确保</span><span>添加单个外部电阻器</span><span>后</span><span>平</span><span>稳</span><span>的输出功率水平，</span><span>无论</span><span>工作输入电压如何</span><span>。</span><span>其他保护</span><span>特性</span><span>包括自动恢复或兼容预</span><span>短路的</span><span>闩锁短路保护</span><span>，和</span><span>可利用</span><span>一</span><span>专用引脚或组合在通用CS引脚上的</span><span>过温保护</span><span>（</span><span>OTP</span><span>）</span><span>。</span></p>
