Abstract:
1. A power conversion apparatus, comprising: a voltage input for receiving an input voltage; a voltage output for supplying an output voltage; circuitry coupled to said voltage input and said voltage output for producing said output voltage in response to said input voltage, said circuitry including a switch having a control input, said switch responsive to said control input for selectively coupling said voltage input to said voltage output; said circuitry including a resistor network connected to said voltage output, said resistor network including a variable resistance element having a control input, said variable resistance element responsive to said control input thereof for establishing a resistance thereof; and said circuitry including a first comparator having a first input connected to said resistor network, a second input for receiving a reference signal, and an output connected to said control input of said switch, wherein said circuitry includes a controller having an input coupled to said voltage output, and said controller having an output connected to said control input of said variable resistance element, said controller responsive to said output voltage for controlling the resistance of said variable resistance element.
