CS5161, CS5161H
CPU 5−Bit Synchronous
Buck Controller
The CS5161/5161H are 5bit synchronous dual NChannel buck
controllers designed to provide unprecedented transient response for
today’s demanding highdensity, highspeed logic. They operate
using a proprietary control method which allows a 100 ns response
time to load transients. The CS5161 is designed to operate over a
916 V range (VCC) using 12 V to power the IC and 5.0 V as the main
supply for conversion.
The CS5161H operates from a 12 V input as the main supply for
conversion using a discrete charge pump circuit to provide up to 20 V
for VCC2 and high side gate drive.
The CS5161/5161H are specifically designed to power
Pentium® III processors and other high performance core logic. They
include the following features: on board 5bit DAC, short circuit
protection, 1.0% output tolerance, VCC monitor, and programmable
Soft Start capability. The CS5161/5161H are available in 16 pin
surface mount packages.

APPLICATIONS INFORMATION
THEORY OF OPERATION
V2 Control Method
The V2 method of control uses a ramp signal that is
generated by the ESR of the output capacitors. This ramp is
proportional to the AC current through the main inductor
and is offset by the value of the DC output voltage. This
control scheme inherently compensates for variation in
either line or load conditions, since the ramp signal is
generated from the output voltage itself. This control
scheme differs from traditional techniques such as voltage
mode, which generates an artificial ramp, and current mode,
which generates a ramp from inductor current.
