1 / 19 page  The CS5132 is a dual output CPU power supply controller. It con- tains a synchronous dual NFET buck controller utilizing the V2 TM control method to achieve the fastest possible transient response and best overall regulation. The CS5132 also contains a second non- synchronous NFET buck con- troller. These synchronous and non-synchronous buck regulators are designed to power the core and I/O logic of the latest high perfor- mance CPUs. The CS5132 incorpo- rates many additional features required to ensure the proper operation and protection of the CPU and power system. The CS5132 dual output provides the industryÕs most highly integrated solution, minimizing external com- ponent count, total solution size, and cost. The CS5132 is specifically designed to power IntelÕs Pentium¨ II pro- cessor and includes the following features: 5 bit DAC and fixed 1.23V reference, Power-Good out- put, hiccup mode overcurrent pro- tection, adaptive voltage position- ing, and overvoltage protection. The CS5132 will operate over an 8.4V to 14V range and is available in 24 lead surface mount package. 1 Features +5V +12V +5V +3.3V (VI/O) VCC(CORE) VID0 VID1 VID3 VID2 VID4 GATE Q3 PCB TRACE (FreeCurrent Sensing Element) 6.6m W L2 3.5 mH MBRD835L VOUT2 10V 510 W VFFB2 2K 1% 1.18K 1% VFB2 COFF2 VCC1 VCC2 LGnd GATE(H) Q1 1.2 mH L1 Q2 GATE(L) COMP2 PCB TRACE (Free Current Sensing Element) 3.3m W 10V 10V 510 W VFFB1 VOUT1 PWRGD OVP COMP1 COFF1 PGnd 23 24 1 2 3 12 11 14 20 16 4 5 21 22 6 8 13 19 17 15 C1 C6-C11 C12 C14 C15 C16 C17 C18-C21 C23-C30 R1 R2 R3 R4 VFB1 7 C3-C5 x 4 510 W R5 510 W R6 FS70VSJ-03 0.1 mF 0.1 mF 1200 mF 1200 mF x 6 1200 mF x 8 680pF 0.1 mF D1 390pF 1 mF 1200 mF x 3 9 18 FS70VSJ-03 FS70VSJ-03 10 10V 10K 100pF 51 W C13 0.1 mF 100 W 0.01 mF 10K R10 C25 R9 R8 R7 C22 +12V C2 1 mF s Synchronous Switching Regulator Controller (VCORE) s Dual N-Channel MOSFET Synchronous Buck Design s V2 TM Control Topology s 200ns Transient Loop Response s 5 bit DAC with 1% Tolerance s Hiccup Mode Overcurrent Protection s 65ns adaptive FET Non-Overlap Time s Non-Synchronous Switching Regulator Controller (VI/O) s Single N-Channel MOSFET buck design s Adjustable Output with 2% Tolerance s System Power Management Pentium¨ II System VCORE and VI/O Controlled by a Single IC Power-Good Output Monitors VCORE Switching Regulator Output OVP Signal Monitors VCORE Switching Regulator Output Package Options Dual Output CPU Buck Controller CS5132 Description Application Diagram 16 15 14 13 12 11 10 1 2 3 4 5 6 7 8 VID2 VID3 VID4 COFF1 COMP1 VOUT1 VFB1 VFFB1 VID1 VID0 PWRGD OVP VCC1 GATEL PGND GATEH LGND VCC2 9 17 18 VFFB2 GATE 19 20 VFB2 COFF2 VOUT2 COMP2 21 22 23 24 24L SO Wide 5V/12V to 2V/16A for Pentium¨II VCC(CORE) , 5V/12V to 3.3V/8A for VI/O Pentium is a registered trademark of Intel Corporation.
