CS5151

www.DataSheet4U.com CS5151 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.
