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…

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…

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…

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？

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

Hi,

What is the approach for using the LT3750 or the LT3751 devices with a charge voltage of 2000V?

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…
