Here is the initial schematic a dual rail CFP cap Mx version.

We will be using the STP110N8F6 ultralow Rdson n channel MOSFET:
https://www.mouser.com/datasheet/2/3...8f6-956395.pdf

Hello x, you might include FDP045N10A / FDI045N10A as alternatives as they have slightly more suitable characteristics.
Although , stock is limited to just 18 qty on mouser. 1000 more might be available by June 15th as per mouser site.

Also STP130N8F7, IPA037N08N3...

regards
Prasi

Thanks for the tip, Prasi. Those do look nice with 5.6mOhm Rdson. I already got my 16 in hand and soldered up. Maybe next set of boards. Although the ones Jhofland spec’d pretty good ones. I forget what the Rdson is big also pretty low.

I got some Texas Instruments CSD19501KCS from Arrow Electronics at a very good reduced price.

Those look pretty nice!

This device seems to be in high demand from all suppliers, Arrow had hundreds of them when I purchased at $0.69 USD each. Now they have practically none left at a higher price now, although they are showing the original ST Micro part with a few hundred in stock at $1.25 USD each.

When I contacted Arrow at purchase they said the prices change every day and it is the manufacturer who sets the price and not Arrow!

So it pays to look around from the usual suppliers when doing a purchase for out of the ordinary type items - especially semi conductors.
