ncv890430: automotive 0.6 a 2 mhz 100% duty cycle step-凯发登录


rev. 1 (658kb)


ncv890430 是一款固定频率、同步降压稳压器,用于在最高 45 v 的输入电压下运行的汽车、电池联接应用。它适用于需要低噪声和低关断电流,还需要以接近输出电压的低输入电压运行的汽车系统。重置引脚(带可调延迟)简化了与微控制器的接口。此零件还具有启用输入,可联接低电压(如微控制器输出)或高电压(如电池输入)和同步输入。ncv890430 还提供汽车电源系统中应具有的若干保护功能,如电流限值、短路保护和高温关断。另外,该开关频率即使在使用小电感器值和全陶瓷输出滤波器电容的情况下也会产生低输出电压波纹,因此形成空间高效的开关稳压器方案。
