The CS5132 is a dual output CPU
power supply controller. It con-
tains a synchronous dual NFET
buck controller utilizing the V
2
TM
control method to achieve the
fastest possible transient response
and best overall regulation. The
CS5132 also contains a second non-
synchronous NFET buck con-
troller. These synchronous and
non-synchronous buck regulators
are designed to power the core and
I/O logic of the latest high perfor-
mance CPUs. The CS5132 incorpo-
rates many additional features
required to ensure the proper
operation and protection of the
CPU and power system. The
CS5132 dual output provides the
industrys most highly integrated
solution, minimizing external com-
ponent count, total solution size,
and cost.
The CS5132 is specifically designed
to power Intels Pentium
¨
II pro-
cessor and includes the following
features: 5 bit DAC and fixed
1.23V reference, Power-Good out-
put, hiccup mode overcurrent pro-
tection, adaptive voltage position-
ing, and overvoltage protection.
The CS5132 will operate over an
8.4V to 14V range and is available
in 24 lead surface mount package.
