同步降压控制器,低电压,带轻型负载能效和瞬变性能增强

Favorite

概览

NCP1589L 是一款低成本 PWM 控制器,运行电压为 5 V 到 12 V。此器件能够产生低至 0.8V 的输出电压,且能基于低至 2.5 V 的电压进行转换。它运行简单,提供了最佳集成水平,减小了电源尺寸,降低了成本。它以斜坡脉冲调制模式运行,可实现卓越的负载步进和释放响应。除了快速瞬变响应之外,它还包括了一个 1.5 A 门极驱动器设计和轻型负载能效特性,如自适应非覆盖电路和二极管仿真。它在连续电流导通模式下的正常运行范围为 200~500 kHz,降低了轻型负载下的电流,进一步实现了节电。保护特性包括可编程过电流保护、输出过电压和欠电压保护,以及输入欠压锁定。
