Abstract:
1. A voltage regulator system for providing a regulated voltage supply for a digital signal processor, said voltage regulator system comprising: a power supply input node for receiving a power supply input voltage; a regulated voltage output node for providing a switched node pulse width modulated regulated output voltage from a switched mode converter to said digital signal processor, said switched mode pulse width modulated regulated output voltage being provided by a pulse width modulation unit; and a feedback circuit coupled to said switched mode pulse width modulated regulated output voltage node and to a control node of said digital signal processor wherein an input voltage is provided by said control node of said digital signal processor, wherein said feedback circuit further includes a first resistor coupled to a feedback node and to said switched mode pulse width modulated regulated output voltage; and a second resistor coupled to said feedback node and to said control node of said digital signal processor wherein said voltage regulator input node provides a non-zero input voltage, and wherein the regulated output voltage node provides the output voltage (V
