HR1001 是一款增强型 LLC 控制器,可提供自适应死区时间调整(ADTA)和容性模式保护(CMP)两个新功能。自适应死区时间调节在 2 个互补栅极输出之间自动插入一个死区时间。这可以在检测半桥转换节点的 dV/dt 电流时让驱动信号保持关断。ADTA 这一特性简化了设计、降低了 EMI 并且提高了效率。HR1001 具有(抗)容性模式保护,可以防止在输出短路或严重过载时发生具有潜在破坏性的容性模式开关。此特性可在异常情况下保护 MOSFET,保障变换器的可靠性。HR1001集成了一个可编程振荡器,用来设置最大和最小开关频率。芯片启动时开关频率被调至最大,然后逐渐降低直至控制环路接管,这样可以防止产生过多的浪涌电流。HR1001 轻载时会进入可控的突发工作模式,能最大限度地减少功耗,并加大输出调节能力。HR1001 具有丰富的保护特性,包括带外部锁定关断的两级过流保护、自动恢复、欠压保护/开启、容性模式保护和过温保护,这些特性能最大限度地减少外部元器件的使用,提高变换器的设计安全性能。
