CPU 4-Bit Nonsynchronous
Buck Controller
The CS5151 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 CS5151 is designed to operate over a
4.25–16 V range (VCC) using 12 V to power the IC and 5.0 V as the
main supply for conversion.
The CS5151 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
circuit protection, 1.0% output tolerance, VCC monitor, and
programmable Soft Start capability. The CS5151 is upward
compatible with the 5–bit CS5156, allowing the mother board
designer the capability of using either the CS5151 or the CS5156 with
no change in layout. The CS5151 is available in 16 pin surface mount
and DIP packages.
