• RE: Any similar projects for Boost Converters?

    On behalf of Anthony Armstrong: 
    The Silent Switcher technology can also be applied in a boost mode topology. I am sure you know that with boost converters, the internal switching in a monolithic die can be very large – depending on how much output current…

  • LT3922 Buck Mode LED Driver

    Hello LT Support,

     

     

    I want to use the LT3922 in Buck Mode as an LED Driver for a 12V/1,5A LED (one power LED). The supply voltage is 15V. Additionally I want to use the SSFM option with up to 2MHz switching frequency (base fsw=1,6Mhz*125%).

  • RE: LT3518 Short-Circuit

    Hello Martin,

    The LT3518 is not designed for short-circuit protection.

    More recent ICs such as the LT3922, LT3795, LT3762, LT3932, LT8391A and other LED drivers now have the short-circuit protection which you are looking for.

    I hope this helps,

    KSz

  • RE: LT3922-1使用BUCK的模式来驱动LED,是否也可以用到25000:1,

    这个片子是针对boost的应用的,只是通过改接电路构建成BUCK应用的,电压反馈要加level shift电路,所以器件多了一点,用在BUCK模式下,可以用到25000:1调光。
