uP9511R 8/7/6/5/4/3/2/1-Phase Synchronous-Rectified Buck Controller for Next Generation GPU Core Power General Description The uP9511R 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 uP9511R 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 uP9511R supports NVIDIA Open Voltage Regulator 8 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 uP9511R adopts continuous total DCR current sensing for load line programming.
