DESCRIPTION OF OPERATION
Schematics of the Si9140 dc-to-dc conversion solutions for
high-performance PC microprocessors are shown in Figure 1
and 2 respectively. These solutions are geared to meet the
extremely demanding transient regulation and power
requirements of these new microprocessors at minimal cost
and with a minimal parts count. The two solutions are nearly
identical, except for slight variations in output voltage, load
transient amplitude, and specified power. Figure 3 is a
schematic diagram for a 3.3-V logic converter.
