CS5151H
CPU 4Bit Nonsynchronous
Buck Controller
The CS5151H is a 4bit nonsynchronous NChannel buck
controller. It is designed to provide unprecedented transient response
for today’s demanding highdensity, highspeed logic. The regulator
operates using a proprietary control method, which allows a 100 ns
response time to load transients. The CS5151H is designed to operate
over a 4.2520 V range (VCC) using 12 V to power the IC and 5.0 V or
12 V as the main supply for conversion.
The CS5151H is specifically designed to power Pentium
processors with MMX Technology and other high performance core
logic. It includes the following features: on board, 4bit DAC, short
circuit protection, 1.0% output tolerance, VCC monitor, and
programmable Soft Start capability. The CS5151H is upwards
compatible with the 5bit CS5156H, allowing the mother board
designer the capability of using either the CS5151H or the CS5156H
with no change in layout. The CS5151H is available in 16 pin surface
mount package.
