Description
CS51313
The CS51313 is a synchronous dual
NFET Buck Regulator Controller. It is
designed to power the core logic of the
latest high performance CPUs. It uses the
V
2
TM
control method to achieve the
fastest possible transient response and
best overall regulation. It incorporates
many additional features required to
ensure the proper operation and protec-
tion of the CPU and Power system. The
CS51313 provides the industry’s most
highly integrated solution, minimizing
external component count, total solution
size, and cost.
The CS51313 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 hiccup mode protec-
tion, over voltage protection, V
CC
moni-
tor, Soft Start, adaptive voltage position-
ing and adaptive FET non-overlap time.
A precision reference trimmed to 1% is
also externally available for use by other
regulators. The CS51313 will operate
over an 8.4V to 14V range and is avail-
able in 16 lead narrow body surface
mount package.
