  • 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.

    主要特性

    • Flash LED driver based on the STCF02 highpower white LED driver
    • The device can operate in five modes which are selected using a combination of logic signals (connected to three enable pins) Five selectable operating modes:Shutdown mode: quiescent current less than 1μA (typical)Shutdown mode with activated negative temperature coefficient (NTC) LED temperature sensing, useful for measuring the temperature before starting both torch and flash modesTorch mode: drives the LED up to 250 mAFlash mode: drives the LED up to 600 mAMiddle flash mode: the current is set between the torch and the flash mode levels
    • A High operating frequency: 1.8 MHz
