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 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 uP9512S supports NVIDIA Open Voltage Regulator with PWMVID feature. The PWMVID input is buffered and filtered to generate accurate referenc.

General Description
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 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 uP9512S 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.
