Synchronous CPU Buck Controller
for 12V Only Applications
Description
The CS51312 is a synchronous dual
NFET Buck Regulator Controller. It is
designed to power the core logic of
the latest high performance CPUs and
ASICs from a single 12V input. It uses
the V
2
TM
control method to achieve
the fastest possible transient response
and best overall regulation. It incor-
porates many additional features
required to ensure the proper opera-
tion and protection of the CPU and
Power system. The CS51312 provides
the industry’s most highly integrated
solution, minimizing external compo-
nent count, total solution size, and
cost.

12V to 16A high performance converter.
The CS51312 is specifically designed
to power Intel’s Pentium
II processor
and includes the following features:
5-bit DAC with 1.2% tolerance,
Power-Good output, overcurrent hic-
cup mode protection, overvoltage
protection, V
CC
monitor, Soft Start,
adaptive voltage positioning, adap-
tive FET non-overlap time, and
remote sense. The CS51312 will oper-
ate over a 9V to 20V (V
CC2
) range
using either single or dual input volt-
age and is available in 16 lead narrow
body surface mount package.
