Texas Instruments LMZ31520/30 SIMPLE SWITCHER® 电源模块
Texas Instruments LMZ31520/30 SIMPLE SWITCHER®电源模块是易用的集成式电源解决方案，它将一块20A或30A的DC/DC转换器、电源MOSFET、一个屏蔽电感以及无源元件组合到一个轻薄的QFN封装内。这个整体电源解决方案仅需三个外部元件，并免除了环路补偿和磁性部件选择过程。15mm x 16mm x 5.8mm QFN 封装可以很轻松地焊接到一个印刷电路板上，并且可实现一个紧凑的负载点设计。可实现 95% 以上的效率，具有超快速负载阶跃响应，以及热阻抗为 8.6℃/W 的出色功率耗散能力。LMZ31520 提供离散负载点设计的灵活性和特性集，非常适合为广泛的集成电路 (IC) 和系统供电。
