    Patent number: 5838151
    Abstract: A power supply (10) including a virtual resistor. The power supply (10) includes (i) a power stage (11) having an input (12) for accepting unregulated power, an output (14) for providing regulated power, a control input (13) and a current sense output (16); (ii) a control circuit (15) including an error amplifier (19) having an inverting input coupled to the output (14) and an output coupled to the control input (13); and (iii) a virtual resistance generator (25) having an input coupled to the output of the error amplifier (19) and an output coupled to a non inverting input of the error amplifier (19). The virtual resistance generator (25) is for supplying a reference voltage (27) to the control circuit (15) such that a voltage present at the output for providing regulated power (14) as a function of current leaving the output for providing regulated power (14) provides an output virtual resistance.
