LTC4110 - Rsns(fet) formula.

Rodrigo on Nov 9, 2020

Hello,

I am using the LTC4110 in my design. To solve the Rsns(fet) formula I need to know the value of Ipri(chg), but there are some variables in the Ipri(chg) formula that I do not know.

The Ipri(chg) formula is:

What the variables N - f and Lpri means?

Thanks in advance,

Rodrigo
