Description
CS5166
The CS5166 is a synchronous
dual NFET Buck Regulator
Controller. It is designed to pow-
er 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 regula-
tion. It incorporates many addi-
tional features required to ensure
the proper operation and protec-
tion of the CPU and power sys-
tem. The CS5166 provides the
industry’s most highly integrat-
ed solution, minimizing external
component count, total solution
size, and cost.
The CS5166 is specifically
designed to power Intel’s
Pentium
II processor and
includes the following features:
5-bit DAC with 1% tolerance,
Power-Good output, adjustable
hiccup mode over-current pro-
tection, V
CC
monitor, Soft Start,
adaptive voltage positioning,
over-voltage protection, remote
sense and current sharing capa-
bility.
The CS5166 will operate over a
4.15 to 14V range and is available
in a 16 lead wide body surface
mount package.
