The CS5151 is a 4-bit nonsyn-
chronous N-Channel buck con-
troller. It is designed to provide
unprecedented transient response
for today’s demanding high-densi-
ty, high-speed logic. The regulator
operates using a proprietary control
method, which allows a 100ns
response time to load transients.
The CS5151 is designed to operate
over a 4.25-16V range (V
CC
) using
12V to power the IC and 5V as the
main supply for conversion.
The CS5151 is specifically designed
to power Pentium
processors with
MMX Technology and other high
performance core logic. It includes
the following features: on board,
4-bit DAC, short circuit protection,
1.0% output tolerance, V
CC
monitor,
and programmable soft start capa-
bility. The CS5151 is upwards com-
patible with the 5-bit CS5156, allow-
ing the mother board designer the
capability of using either the
CS5151 or the CS5156 with no
change in layout. The CS5151 is
available in 16 pin surface mount
and DIP packages.
