ST L5963集成LDO和HSD的双路开关稳压器解决方案
ST公司的L5963是双路单片开关稳压器,包括两个开关模式同步降压转换器,线性稳压电源(LDO)和高边驱动器(HSD)和电压检测器.为了保证鲁棒工作,所有的输出都有单独的热保护和电流限制.满足AEC-Q100,输入电压从3.5V到26V,集成了高边/低边NDMOS,输出大于1V,负载电流3.0A,主要用在汽车电子.本文介绍了L5963主要特性,功能框图和应用电路,以及评估板EVAL-L5963和EVAL-L5963Q主要特性,电路图和PCB设计图.
The L5963 integrates two switching mode synchronous step down converters, a linearly regulated power supply, a protected high side driver and voltage detectors. To guarantee a robust operation, all the outputs have independent thermal protection and current limitation.
