面向升压型单信道大屏幕的白色LED驱动器_BD9413F

BD9413F是白色LED用高效率驱动器,适用于大屏幕液晶驱动器。BD9413F内置了可向光源(LED串联连接的阵列)提供适当电压的DC/DC转换器。 BD9413F中内置了应对异常状态的几种保护功能。过电压保护(OVP: over voltage protection), 过电流检测(OCP: over current limit protection of DC/DC), LED过电流保护(LEDOCP: LED over current protection), 过升压保护(FBMAX: over boost protection)等。因此,可在更宽的输出电压条件及负载条件下使用。
