DC/DC型 面向大屏幕的白色LED驱动器 BD9428

BD9428是白色LED用高效率驱动器,适用于大屏幕液晶驱动器。BD9428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。BD9428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 DCDC)、短路电路保护(SCP: short circuit protection)、开路保护(open detection of LED string)等。因此,可在更宽的输出电压条件及负载条件下使用。
