R1278S Series AEC-Q100 Grade 1 30 V, 2 A Synchronous PWM Step-down DC/DC Converter for Automotive Applications
●概述：
■R1278S是一款最大额定电压为36V的同步降压DC/DC转换器，内置驱动器。工作频率为2 MHz，采用扩频时钟发生器，对AM频带的干扰影响很小。在起动条件下，开关频率会自动降低，以保持输出电压电平恒定。
●主要优势：
■提供2 MHz的高开关频率，效率为87%。
■通过将开关频率降低到最小1/4来保持起动时的输出电压恒定。
■通过使用扩频时钟发生器实现EMI降噪。（扩散率：+10%）。
