The CS5155 is a 5-bit synchronous
dual N-Channel buck controller. It
is designed to provide unprece-
dented transient response for
todays demanding high-density,
high-speed logic. The regulator
operates using a proprietary control
method, which allows a 100ns
response time to load transients.
The CS5155 is designed to operate
over a 4.25-14V range (V
CC
) using
12V to power the IC and 5V as the
main supply for conversion.
The CS5155 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
CS5155 is backwards compatible
with the 4 bit CS-5150, allowing the
mother board designer the capabili-
ty of using either the CS-5150 or the
CS5155 with no change in layout.
The CS5155 is available in 16 pin
surface mount and DIP packages.
