CS5155
CPU 5âBit Synchronous
Buck Controller
The CS5155 is a 5âbit synchronous dual NâChannel buck
controller. It is designed to provide unprecedented transient response
for todayâs demanding highâdensity, highâspeed logic. The regulator
operates using a proprietary control method, which allows a 100 ns
response time to load transients. The CS5155 is designed to operate
over a 4.25â14 V range (VCC) using 12 V to power the IC and 5.0 V 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 features: on board, 5âbit DAC, short circuit protection,
1.0% output tolerance, VCC monitor, and programmable Soft Start
capability. The CS5155 is backwards compatible with the 4âbit
CS5150, allowing the mother board designer the capability of using
either the CS5150 or the CS5155 with no change in layout. The
CS5155 is available in 16 pin surface mount and DIP packages.
