CS5150H
CPU 4âBit Synchronous
Buck Controller
The CS5150H is a 4âbit 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 CS5150H is designed to operate
over a 4.25â20 V range (VCC) using 12 V to power the IC and 5.0 V or
12 V as the main supply for conversion.
The CS5150H is specifically designed to power Pentium® Pro
processors and other high performance core logic. It includes the
following features: on board, 4âbit DAC, short circuit protection,
1.0% output tolerance, VCC monitor, and programmable Soft Start
capability. The CS5150H is upward compatible with the 5âbit
CS5155H, allowing the mother board designer the capability of using
either the CS5150H or the CS5155H with no change in layout. The
CS5150H is available in 16 pin surface mount.
