1. A bounded droop voltage circuit for use with a power supply providing a regulated output voltage signal to a load, said droop voltage circuit comprising:

  • a first circuit to generate a droop current signal proportional to a load current drawn from said regulated output voltage signal; and

    a second circuit to generate a droop voltage signal based on said droop current signal to cause the power supply to reduce said regulated output voltage signal by an amount corresponding to said droop voltage signal, said second circuit including a limiting circuit to bound said droop voltage signal to a maximum value independent of the load current.
