Synchronous CPU Buck Controller
for 12V and 5V Applications
Description
The CS51311 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 fea-
tures required to ensure the proper
operation and protection of the CPU
and Power system. The CS51311 pro-
vides the industry’s most highly inte-
grated solution, minimizing external
component count, total solution size,
and cost.
