STEVAL-TLL003V1评估板是专门为闪存设计,使用STCF02升压/掉电电流模式转换器,提供PCB布局和外部元件的正确建议的LED驱动器。该设备可以在其中使用的逻辑信号的组合(连接到3的使能引脚)中选择五种模式操作。This evaluation board is dedicated to the design of a flash LED driver using the STCF02 step-up/ down current mode converter, providing the proper recommendations for PCB layout and external components. The device can operate in five modes which are selected using a combination of logic signals (connected to three enable pins). Also implemented is a simple programmable RC circuit used to shut down the device to prevent LED burning during flash mode in the event of microcontroller fault. This evaluation board drives a single flash LED with a forward voltage range of 2.7 to 5 V.
