CS5151H

CPU 4-Bit Nonsynchronous

Buck Controller

The CS5151H is a 4–bit nonsynchronous 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 CS5151H is designed to operate

over a 4.25–20 V range (V ) 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, 4–bit DAC, short

programmable Soft Start capability. The CS5151H is upwards

compatible with the 5–bit 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.
