    Description

    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 reference voltage and the output voltage is precisely regulated to the reference input.
    The uP9511 adopts continuous total DCR current sensing for load line programming. The uP9511 provides hardware setting to adjust the operating phase number in different load current state. The uP9511 uses MOSFET RDS(ON) current sensing for channel current balance.

    if I was younger that would be my nightmare about looks at almost 70. Please stop scaring people and their kids. Mirror is bad enough.
