此评估板的用途是提供使用 ALED7707 芯片的六通道中等电流 led 驱动器的应用示例。单片升压转换器提供从单个电源导轨开始的所需 led 电源电压、而连接到六个输出的 led 串的亮度通过 pwm 信号控制。检测并管理开路 led 和 led 短路故障情况。该板设计用于为汽车应用提供紧凑型参考解决方案、涉及多串排列的多个 led (例如内部照明、信息娱乐 lcd 背光等)。
宽输入电压 6 V 至 32 V
六个 70 毫安输出通道(每个通道可达 30 毫安至 85 毫安)
pwm 亮度控制( 10 μs 最小调光接通时间)
每个通道多达 10 个白色 led ( 36 v 额定电压)
>90% 效率( vin = 12 v 、 vboost = 30 v 、 fsw=1 mhz 、无减震器)
板载输入滤波器、用于传导 emi 减少
