CS5156H
CPU 5−Bit Nonsynchronous Buck Controller
The CS5156H is a 5−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 CS5156H 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 CS5156H 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.
