uP9512Q - 4/3/2/1-Phase Synchronous-Rectified Buck Controller

Datasheet Summary

Features

  • The uP9512Q is a 4/3/2/1-phase PWM controller specifically designed to provide high-precision output voltage system for next generation GPUs. The uP9512Q 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 uP9512Q supports NVIDIA Open Voltage Regulator with PWMVID feature. The PWMVID input is buffered and filtered to generate accurate referenc.

uP9512Q 4/3/2/1-Phase Synchronous-Rectified Buck Controller with SMBus Digital Interface General Description Features The uP9512Q is a 4/3/2/1-phase PWM controller specifically designed to provide high-precision output voltage system for next generation GPUs. The uP9512Q 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 uP9512Q 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.
