In the above calculation the R
of 0.065
was multiplied by a factor of 1.7 to obtain R
in
DS (ON)
ON
order to account for some temperature rise of the MOSFETs. (R
typically increases by a
DS (ON)
factor of 1.7 for a typical MOSFET as temperature increases from 25ºC to 170ºC.)
So,
= P
/P
= 100/109.05 = 92%

This compares favorably to the measured efficiency (see Typical Performance graphs).
