The CS5156 is a 5-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 CS5156 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 CS5156 is specifically designed
to power Pentium
II processors
and other high performance core
logic. It includes the following fea-
tures: on board, 5-bit DAC, short
circuit protection, 1.0% output tol-
erance, V
CC
monitor, and pro-
grammable soft start capability. The
CS5156 is backwards compatible
with the 4-bit CS5151, allowing the
mother board designer the capabili-
ty of using either the CS5151 or the
CS5156 with no change in layout.
The CS5156 is available in 16 pin
surface mount and DIP packages.
