技术问答

全球领先的半导体解决方案主要供应商瑞萨（RENESAS）电子，2018年4月25日宣布推出三款可编程电源管理IC（PMIC）——ISL91302B、ISL91301A和ISL91301B。它们可以为智能手机和平板电脑中的应用处理器提供最高的电源效率和最小的展板体积，还可以为人工智能（AI）处理器、FPGA和工业微处理器（MPU）提供电源管理。这三款可编程电源管理IC非常适合为固态驱动器（SSD）、光收发器和各种消费类电子产品、工业以及网络设备中的各路负载供电。其中，ISL91302B双/单输出多相PMIC可在70mm²解决方案尺寸下提供高达20A的输出电流和94％的峰值效率，比同类PMIC小40％以上。

除ISL91302B外，瑞萨的ISL91301A三相输出PMIC和ISL91301B四相输出PMIC均可提供高达16A的输出功率，峰值效率达94％。这些新型可编程PMIC利用瑞萨专有的R5调制技术在负载瞬变期间提供快速的单周期瞬态响应、数字调谐补偿和超高6MHz（最大）的开关频率。这些特性使得电源设计人员可以更轻松地设计2mm x 2mm，高度为1mm的薄型电感器、小型电容器以及仅有少量无源元件的电路板。

瑞萨的PMIC也不需要外部补偿元件或外部分压器来设置工作条件。每个PMIC都可在全负载电流范围内动态改变有效相的数量以获得最佳效率。其低静态电流、出色的轻载效率、稳压精度和快速的动态响应显著延长了目前市场上功能丰富、耗电量大的设备的电池寿命。

智能手机和平板电脑应用处理器需要更小尺寸的电源和更高的输出电流和效率，以最大限度延长电池寿命，ISL91302B和ISL91301A/B PMIC为设计人员提供了有效的解决方案，以解决最棘手的PCB布局、动态扩展性能和延长电池运行时间的问题。
