Verify that the leading edge current spike is below the
allowed current limit envelope (see Figure 52) for the drain
current waveform at the end of the 220 ns blanking period.
3.Thermal check – At maximum output power, minimum
input voltage and maximum ambient temperature, verify
that temperature specifications are not exceeded for
TOPSwitch-GX
, transformer, output diodes and output
capacitors. Enough thermal margin should be allowed for
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
Figure 49. Layout Considerations for TOPSwitch-GX using R Package.
