the part-to-part variation of the R
of
TOPSwitch-GX
as specified in the data sheet. The margin required can
either be calculated from the tolerances or it can be
accounted for by connecting an external resistance in
series with the DRAIN pin and attached to the same
heatsink, having a resistance value that is equal to the
difference between the measured R
of the device
under test and the worst case maximum specification.
