CS5157 Overview

1.5 A SWITCHING CONTROLLER, PDSO16

CS5157
CPU 5−Bit Synchronous
Buck Controller
The CS5157 is a 5−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 CS5157 is designed to operate
over a 4.25−16 V range (V
CC
) using 12 V to power the IC and 5.0 V as
the main supply for conversion.
The CS5157 is specifically designed to power Pentium® II
processors and other high performance core logic. It includes the
following features: on board, 5−bit DAC, short circuit protection,
1.0% output tolerance, V
CC
monitor, and programmable Soft Start
capability. The CS5157 is available in 16 pin surface mount.
