Abstract:
In one embodiment, a control circuit adjusts a duty cycle of a boost converter and comprises a duty cycle limiter generator configured to receive an input voltage provided to the boost converter and to generate a control signal to be provided to the boost converter for adjusting the duty cycle of the boost converter to control the output voltage of the booster converter in response to the input voltage. In one embodiment, the maximum duty cycle limit generator further generates the maximum duty cycle signal in response to an output voltage of the boost converter.
