    摘要： 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.

    摘要： In one embodiment, a switching regulator includes an inductor, a first switch, and a second switch. The first and second switches generate current in the inductor. Inductor current may flow through the second switch with both a positive and negative polarity. Voltages on terminals of the second switch may be sensed, and an offset applied to generate a level shifted signal. In one embodiment, the switching regulator is a boost switching regulator, and the offset is generated using a current source. Matched MOS transistor switches may be used to couple voltages on terminals of the second switch to amplifier inputs, and the offset is introduced across an MOS switch coupled between one amplifier input and the output.
