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

Key Features

  • include adjustable soft-start, channel current limit, under voltage protection, over voltage protection and power good output. The uP9511R is available in VQFN5x540L package. Ordering Information Features † Support NVIDIA’s Open VReg Type 8 PWMVID Technology † Selectable 8/7/6/5/4/3/2/1-Phase Operation by Hardware Setting † Differential Remote Voltage Sensing † Continuous Inductor DCR Current Sensing Voltage Adjustment † Switching Frequency Adjustment † Operating Phase Number Adjustment † Adjus.
