uP9511 - 8/7/6/5/4/3/2/1-Phase Synchronous-Rectified Buck Controller

Key Features

  • The uP9511 is an 8/7/6/5/4/3/2/1-phase PWM controller specifically designed to provide high-precision output voltage system for next generation GPUs. The uP9511 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 uP9511 supports NVIDIA Open Voltage Regulator 8 with PWMVID feature. The PWMVID input is buffered and filtered to generate accurate.
