Si8250/1/2
In both cases, the bias supplies must be filtered using
low ESR/ESL capacitors placed close to the IC pins.
Thick copper traces should be connected to the bias
pins (V
reduce resistance and inductance. The copper routings
from the drivers to the FETs should be kept short and
wide, especially in very high frequency applications, to
reduce inductance of the traces so that the drive signals
can be kept clean. Connections between V
the output voltage must be kept as short as possible to
minimize inductance and parasitic ringing effects.

It is best to locate the Si8250/1/2 as close to the output
voltage terminal as possible and use a Kelvin
connection to reduce the difference in ground potential
between the Si8250/1/2 and the output voltage ground
return. Most applications will require access to the
debug pins. These pins are susceptible to damage from
