The CS5132H is a dual output CPU
power supply controller. It con-
tains a synchronous dual NFET
buck controller utilizing the V2
TM
control method to achieve the
fastest possible transient response
and best overall regulation. The
CS5132H also contains a second
nonsynchronous NFET buck con-
troller. These synchronous and
nonsynchronous buck regulators
are designed to power the core and
I/O logic of the latest high perfor-
mance CPUs. The CS5132H incor-
porates many additional features
required to ensure the proper
operation and protection of the
CPU and power system. The
CS5132H dual output provides the
industry’s most highly integrated
solution, minimizing external com-
ponent count, total solution size,
and cost.
The CS5132H is specifically
designed to power Intel’s
Pentium II processor and
includes the following features:
5-bit DAC and fixed 1.23V refer-
ence, Power-Good output, hiccup
mode overcurrent protection,
adaptive voltage positioning, and
overvoltage protection.
The CS5132H will operate over an
8.4V to 20V range and is available
in 24 lead surface mount package.
