CS5156

www.DataSheet4U.com CS5156 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. http://onsemi.com MARKING DIAGRAMS 16 16 CS5156 AWLYWW 1 1 SOIC−16 D SUFFIX CASE 751B Features N−Channel Design Excess of 1.0 MHz Operation 100 ns Transient Response 5−Bit DAC Backward Compatible with 4−Bit CS5150/CS5151 30 ns Gate Rise/Fall Times 1.0% DAC Accuracy 5.0 V & 12 V Operation Remote Sense Programmable Soft Start Lossless Short Circuit Protection VCC Monitor Adaptive Voltage Positioning V2™ Control Topology Current Sharing Overvoltage Protection ...
