面向升压型单信道大屏幕的白色LED驱动器_BD9285F

BD9285F是白色LED用高效率驱动器,适用于大屏幕液晶驱动器。BD9285F内置了可向光源(LED串联连接的阵列)提供适当电压的DCDC转换器。
BD9285F中内置了应对异常状态的几种保护功能。过电压保护(OVP: over voltageprotection ) 、过电流检测(OCP: over current limitprotection of DCDC)、LED过电流保护(LEDOCP: LEDover current protection)、开路保护(open detectionof LED string)等。因此,可在更宽的输出电压条件及负载条件下使用。
