CPU 5−Bit Nonsynchronous
Buck Controller
The CS5156 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 CS5156 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 CS5156 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 CS5156 is backwards compatible with the 4−bit
CS5151, allowing the mother board designer the capability of using
either the CS5151 or the CS5156 with no change in layout. The
CS5156 is available in 16 pin surface mount and DIP packages.
