LITIX™ Power Flex

综述

LED光源在汽车前端照明中有着广泛的应用。LED节能环保且元件体积小，便于布置造型，有利于实现多种新颖的车灯设计，如LED矩阵和激光远光灯等。这样的设计趋势要求相应DC/DC驱动器高度灵活，以高效驱动功率高达50W（或电流大于3A）的LED系统。英飞凌现已推出全新的多拓扑结构DC/DC控制器LITIX™ Power Flex。作为该系列的首款产品，TLD5541-1QV采用同步DC/DC H桥拓扑结构，能以超过90%的系统能效驱动大功率LED，而且只需极少的外围器件。该器件优化了扩频开关频率，因而降低了电磁辐射。另外，得益于无缝升降压调节和快速动态负载跳变，仅用一片TLD5541-1QV驱动两三个甚至多个独立开关的LED负载便能实现低成本且带完整保护诊断功能的LED车灯设计，同时最高支持55V的串联电压。
