uP9512S Datasheet | uPI Semiconductor

Description Features The u P9512S is a 4/3/2/1-phase PWM controller specifically designed to provide high-precision output voltage system for next generation GPUs. The u P9512S provides programmable output voltage and active voltage positioning functions to adjust the output voltage as a function of the load current, so it is optimally positioned for a load current transient. The u P9512S supports NVIDIA Open Voltage Regulator with PWMVID feature . The PWMVID input is buffered and filtered to generate accurate reference voltage and the output voltage is precisely regulated to the reference input. The integrated SMBus interface provides user the flexibility to optimize the performance and efficiency. The u P9512S uses per-channel inductor DCR current sensing for channel current balance and channel current limit. The continuous total DCR current sensing is used for load line programming and total output current protection. The u P9512S also provides hardware setting to adjust the operating phase number in different load current state. Other features include under voltage protection, over voltage protection and power good output. The u P9512S is available in a WQFN4x4-32L package. † Support NVIDIA’s PWMVID Technology † SMBus Interface for Performance and Efficiency Optimization - Dynamic Programmable VR Parameters - Programmable Protection Thresholds - VR Output Reporting † Selectable 4/3/2/1-Phase Operation by Hardware Setting † Support up to 2MHz Operation Frequency † Continuous Inductor DCR Current Sensing † Auto-Phase Shedding † Power State Input (PSI) † Power Good Indication † Channel Current Limit Protection † Total Output Over Current Protection † Over/Under Voltage Protection † Over Temperature Protection † Ro HS pliant and Halogen Free Pin Configuration P EAP DAC VINMON ADDR/FSW IMON LPC VOUT Ordering Information Order Number u P9512SQKI Package WQFN4x4 - 32L Top Marking u P9512S Note: (1) Please check the sample/production availability with u PI representatives...
