1 / 24 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 9 1 Publication Order Number: CS5307/D CS5307 Four−Phase VRM 9.0 Buck Controller Multiphase controllers provide fast, accurate regulation with the control features required to power the next generation of processors in desktop, workstation and server applications. Combined with external gate drivers and power components, the CS5307 implements a compact, highly integrated buck converter. Enhanced V2™ control inherently compensates for variations in both line and load. Current sharing between phases is achieved by Peak Current Sharing. The CS5307 includes Power Good with a programmable lower threshold. Applications include Embedded Processor Power and low voltage/high current power supplies. Features • Switching Regulator Controller − Lossless Current Sensing − Enhanced V2 Control Method Provides Excellent Regulation and Fast Transient Response − Programmable 200 to 800 kHz Switching Frequency (Per Phase) − Duty Cycle − 0% to 100% − Programmable Adaptive Voltage Positioning Reduces Output Capacitor Requirements − Programmable Soft Start • Accurate Current Sharing • Protection Features − Pulse−by−Pulse Current Limit for Each Phase − Programmable Hiccup Overcurrent Protection − All “1” DAC Code Fault − Processor Overvoltage Protection through Bottom MOSFETs − Undervoltage Lockout • System Power Management − 5−Bit DAC With 1.0% Tolerance Compatible with VRM 9.0 − Power Good Output − Programmable Power Good Lower Threshold − Guaranteed Startup at −20°C PIN CONNECTIONS MARKING DIAGRAM A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week SO−24L DW SUFFIX CASE 751E 1 24 1 CS5307 AWLYYWW 24 VID1 CSREF VID0 CS4 PWRGDS CS3 GATE4 CS2 GATE3 CS1 GATE2 ROSC GATE1 OCSET VCC GND VID2 VDRP VID3 VFB 124 PWRGD SS VID4 COMP Device Package Shipping ORDERING INFORMATION CS5307GDW24 SO−24L 30 Units/Rail CS5307GDWR24 SO−24L 1000 Tape & Reel http://onsemi.com |
