说明

MAX20019/MAX20020为2.2MHz和3.2MHz、双通道、降压型转换器,集成高边和低边MOSFET。高压降压型转换器设计用于在高达17V输入电压下连续工作。输出电压由工厂预设。Buck 1预设为3.3V、3.0V或2.8V。Buck 2预设为1.8V、1.5V、1.2V或1V。另一选项为Buck 1设为5V,Buck 2设为3.3V。

低压buck具有固定频率PWM工作模式,开关频率为2.2MHz或3.2MHz。高频操作实现全陶瓷电容设计,允许使用小尺寸外部元件。片上低阻开关在确保高效的同时最大程度降低寄生电感。MAX20019上的500mV使能滞回允许使用低成本、长线同轴电缆,即使在低速启动情况下也没问题。MAX20020的Buck 1在VSUP高于5.5V后启动,Buck 1由EN输入驱动。

安全特性包括:过压(OV)保护、逐周期限流,以及带自动恢复功能的热关断保护。buck转换器彼此180°错相工作,最大程度降低输入电流纹波。
