BD9416FS
升压型双信道 面向大屏幕的白色LED驱动器
BD9416FS是白色LED用高效率驱动器,适用于大屏幕液晶驱动器。BD9416FS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。BD9416FS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)、LED 过流保护(LEDOCP: LEDOver 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。
