CS5157

www.DataSheet4U.com CS5157 CPU 5−Bit Synchronous Buck Controller The CS5157 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 CS5157 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 CS5157 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 CS5157 is available in 16 pin surface mount. http://onsemi.com MARKING DIAGRAM 16 16 CS5157 AWLYWW 1 1 SOIC−16 D SUFFIX CASE 751B Features Dual N−Channel Design Excess of 1.0 MHz Operation 100 ns Transient Response 5−Bit DAC 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 25 ns FET Nonoverlap Time V2™ Control Topology Current Sharing Overvoltage Protection A WL, L YY, Y WW, W = Assembly Location = Wafer Lot = Year = Work Week PIN CONNECTIONS VID0 VID1 VID2 VID3 SS VID4 COFF VFFB 1 16 VFB COMP LGND VCC1 VGATE(L) PGND VGATE(H) VCC2 ORDERING INFORMATION Device CS5157GD16 CS5157GDR16 Package...
