Surge Current Guidelines
This section provides the results of a worst case, surge
current analysis. The analysis determines the maximum
amount of surge current that the Pentium
II processor
mobile module can manage.
In the analysis, the Pentium II processor mobile module has
two 4.7
μ
f with an ESR of 0.15
s each. The MMC-1 is
approximately 30 m
of series resistance, for a total series
resistance of .18
. If the user powers the system with the
A/C adapter (18V), the amount of surge current on the
module would be approximately 100A.
This information was also used to develop I/O bulk
capacitance requirements (See Table 20).
NOTE
: Depending on the system electronics design,
different impedances may yield different results. The OEM
should perform a thorough analysis to understand the
implications of surge current on their system.
Figure 6 shows an electrical model used when analyzing
instantaneous power-on conditions and Figure 7 illustrates
the results with a SPICE simulation.
