• 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 - using at constant frequency

    Hello,

    I'd like to use the LT3750 to charge a capacitor using a specific transformer which requires a 100kHz frequency.

    As this controller doesn't have the ability to configure the frequency - is there a way to do it using one of the pins. Now the…

  • LT3750 - controlling the capacitor charging current

    Hello,

    I'm using the LT3750 to charge a capacitor to 240V from a 8VDC source.

    The capacitor is charged in ~200msec to the target voltage with an input current (from the 8V) of 1.1A and slowly decrease to ~0.6A.

    I'd like to decrease the input current…

  • 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?

  • 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

  • Lt375x At Higher Voltage

  • 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.

  • 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…

  • RE: Synchronized and isolated capacitor charger

    Hi Julia,

    Request is very interesting.  It has several items that are unique:

    1. Synchronizing an isolated supply is very rare.
    2. Isolated current sources are very rare.
    3. Based on the wide output range, some form of flyback will be needed.

    Short answer, we…
