the part-to-part variation of the R

DS(ON) 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

DS(ON) of the device under test and the worst case

maximum specification.
