CS5150
CPU 4−Bit Synchronous
Buck Controller
The CS5150 is a 4−bit synchronous dual N−Channel buck
controller. It is designed to provide unprecedented transient response
for today’s demanding high−density, high−speed logic. The regulator
operates using a proprietary control method, which allows a 100 ns
response time to load transients. The CS5150 is designed to operate
over a 4.25−16 V range (V_CC) using 12 V to power the IC and 5.0 V or
12 V as the main supply for conversion.
The CS5150 is specifically designed to power Pentium® Pro
processors 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
capability. The CS5150 is upward compatible with the 5−bit
CS5155H, allowing the mother board designer the capability of using
either the CS5150 or the CS5155 with no change in layout. The
CS5150 is available in 16 pin surface mount.
