uP9512S Datasheet | uPI Semiconductor

Key Features

• The uP9512S is a 4/3/2/1-phase PWM controller specifically designed to provide high-precision output voltage system for next generation GPUs
• The uP9512S supports NVIDIA Open Voltage Regulator with PWMVID feature
• The integrated SMBus interface provides user the flexibility to optimize the performance and efficiency
• The uP9512S 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 uP9512S 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
