Hi there.
Looking at the schematic (http://cds.linear.com/docs/Datasheet/3471fb.pdf) on page 16, I am asking myself what kind of diodes are recommended for a boost topology.
It is certain that it should be a fast switching diode, its capacity should be as low as possible.
What I am in doubt of...
Of course I know about setting the feedback ratio using the voltage divider, this is a fundametal of the LT3471.
Anyway thank You for that advise.
In the meantime I have found another solution for limiting the switching current.
Actually I should have thought about it earlier..
By using a RC...
Hi there.
Looking at page 16 of this datasheet: http://cds.linear.com/docs/Datasheet/3471fb.pdf
I am wondering if I could lower the Voltage at pins 10 & 6 using some diodes in series.
Why I want to do so: (Just looking at one part, namely the positive voltage)
The internal switching...
Hello out there.
I am wondering if I could build some device based on optocouplers (or other solution),
to seperate a USB device from the PC to make it potential free.
Of course the device to be seperated could not be powered via USB.
In other case I would be forced to use at least a...
The high current occurs as high peaks (in simulation).
I think that even if there are onyl small peaks the core could get saturated if I dont choose a proper one.
Have already seen inductors with I_sat about 10A
Maybe I should look for a transformer to have three coils on one core...
I am...
Hello.
I am looking for a Inductor which I want to use in a SEPIC DC/DC Converter.
What I need are thre coils (each 25uH) at one core.
Saturation current and resonance frequency are not exactly specified yet.
After simulating the whole thing with LTspice I_sat turned out the be about 9A.
Not...
Thank You.
Especially for that Application Note. Which is very useful and helps to calculate the proper values.
Besides it makes clear the functionality of a SEPIC converter in detail :)
Best regards,

Hello.
If You look at Page 32 of this Datasheet: http://cds.linear.com/docs/Datasheet/3757fa.pdf, there is the LT3757 as a SEPIC Converter, delivering +-0.4A at +-12V.
Could You tell me if it
