• LT3750

    Hello, I am working on a cap charger for an avoinics power supply design.  We need to run from a 280VDC bus to charge 20,000uF of cap from 0-280V with a max current of 30A (time is less of an issue).  I am looking at the LT3750 or LT3751 but have several…

  • LT3750 - maximum voltage on RDCM and RVOUT pins

    Hello,

    The maximum voltage on the RDCM and RVOUT pins isn't specified in the LT3750's datasheet/

    In the  LT3751 I can see a 60V clamping diode, but it's not the same in the LT3750/

    So, what is it for the LT3750?

    Thanks

  • RE: Best product choice for capacitor charging?

    Hi,

    Please consider the LT3750 or the LT3751. The LT3751 is the newer part with additional protection features.

  • RE: LT3750 - controlling the capacitor charging current

    I did not find corresponding expression in LT3750 DS. By meantime, please use formula of page 15 DS LT3751, Choosing Capacitor Charger IPK. I'll refer your question to the IC designer for conformation. 

  • Charging 350V, 4mF capacitor bank using LT3750?

    Hi, I am looking to charge a capacitor bank with a rated voltage of 350V and total capacitance of 4mF . I wonder if it is ok to use LT3750 ?The charge of a capacitor bank is used to discharge a flash xenon lamp?

  • LT3420 as HV power supply. 

    I need a HV (250-300V) power supply to bias an avalanche photo-diode (current ~1 mA max).  The spec sheet of the LT3420 says it can be used as a supply but there are no details.  Is it possible to have it always charging?  And not have the charging block…
