Hi,
I designed a DC-DC converter and for the MOSFET driver (TLP250) I need 2 MINMAX for isolated power source (12volt). However, I don't know which MINMAX is suitable for my circuit. There are many MINMAX with a wide range of power. why the power of a MINMAX is important? How its output current should be considered?
I am thankful if someone gives me instructions for using MINMAX in a DC-DC converter.
Thank you so much

 

Your post makes no sense, what is this MINMAX? Show your circuit so we can tell what you mean.

 

Most probably fixed voltage switching regulators with Vo= 3,3, 5 or 12V.

 

As atferrari mentions, probably the product line name for a family of switching regulators.

But without a schematic datasheet or at least a web page link, all we can do here is twiddle our thumbs.

Thanks ST, now I know how to say it in English. Not sure to have an elegant expression to say it in Spanish.

 

My meaning as MINMAX is a DC-DC regulator for providing an isolated DC voltage for a MOSFET driver to switch a MOSFET. I put the link of a MINMAX which converter a 12 volt to isolated 12 volt.

Please note that I need two MINMAX IC to have two isolated power supply for TLP250 (MOSFET Driver).
This is the picture of my circuit

As it is clear there are 3 distinctive ground (N, M, and P). The N is the main ground of the system. The M and P are the groud of the two isolated power supply which will be provided by MINMAX IC.

 

I am so thankful if you let me know which ampere is needed for the gate of an IRFP250M MOSFET.
In this regard, I can select the needed MINMAX.
