uP9512R

8 Phase Buck Controller with SMBus; • Support NVIDIA’s Open VReg Type 4i+ PWMVID Technology\n• SMBus Interface for Performance and Efficiency Optimization \n• Dynamic Programmable VR Parameters\n• Programmable Protection Thresholds\n• VR Output Reporting\n \n• Selectable 8/7/6/5/4/3/2/1-Phase Operation by Hardware Setting\n• Support up to 2MHz Operation Frequency\n• Continuous Inductor DCR Current Sensing\n• Auto-Phase Shedding\n• Adjustable Soft-Start Time\n• Power State Input (PSI)\n• Power Good Indication\n• Channel Current Limit Protection\n• Total Output Over Current Protection\n• Over/Under Voltage Protection\n• Over Temperature Protection\n• RoHS Compliant and Halogen Free;

The uP9512R is an 8/7/6/5/4/3/2/1-phase PWM controllerspecifically designed to provide high-precision outputvoltage system for next generation GPUs. The uP9512Rprovides programmable output voltage and active voltagepositioning functions to adjust the output voltage as afunction of the load current, so it is optimally positioned fora load current transient.\n\n The uP9512R supports NVIDIA Open Voltage Regulatortype 4i+ with PWMVID feature. The PWMVID input isbuffered and filtered to generate accurate reference voltageand the output voltage is precisely regulated to the referenceinput. The integrated SMBus interface provides user theflexibility to optimize the performance and efficiency.\n\n The uP9512R uses per-channel inductor DCR currentsensing for channel current balance and channel currentlimit. The continuous total DCR current sensing is usedfor load line programming and total output current protection.The uP9512R also provides hardware setting to adjust theoperating phase number in different load current state.\n\n Other features include adjustable soft-start, under voltageprotection, over voltage protection and power good output.The uP9512R is available in a VQFN5x5-40L package.\n\n
