  • Commodity Description
Texas Instruments LM5122 同步升压控制器是一款支持多相位的同步升压控制器,用于高效同步升压应用。此控制方法基于峰值电流模式控制。电流模式控制可提供内部线路前馈、逐周期电流限制和简化的环路补偿。可将开关频率设定至高达 1MHz。通过两个稳健耐用 N 沟道 MOSFET 栅极驱动器来实现更高效率。一个用户可选二极管仿真模式还可实现断续模式运行,以提高轻负载时的效率。一个内部电荷泵可针对高侧同步开关实现 100% 占空比(旁路运行)。一个 180º 相移时钟输出可实现简单多相位交叉配置。其他特性包括热关断、频率同步、断续模式电流限制和可调线路欠压闭锁。 了解更多
