1/02

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.
