CS5157H
CPU 5−Bit Synchronous
Buck Controller
The CS5157H 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 CS5157H is designed to operate
over a 4.25−20 V range (VCC) using 12 V to power the IC and 5.0 V or
12 V as the main supply for conversion.
The CS5157H 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, VCC monitor, and programmable Soft−Start
capability. The CS5157H is available in 16 pin surface mount.
