Patent ID: 7342388

Claim:
A pulse width modulation DCDC converter controller for controlling the voltage on a line responsive to a state of the line comprising: an analog to digital converter (ADC) for coupling to the line; a pulse width modulation (PWM) controller coupled to an output of the ADC to provide output pulses for controlling a switching converter circuit; a line sensor for coupling to and sensing a state of the line, including a voltage on the line; the PWM controller being coupled to an output of the line sensor and responsive to a plurality of ranges of the difference between a target voltage for the line and the voltage on the line, each range having associated therewith a step size and a skip step size, the PWM controller being configured to repetitively provide a number of equal pulse width pulses for coupling to a switching converter circuit responsive to the skip step size for a current range, the pulses being adjusted in pulse width relative to a previous pulse width responsive to the step size for the current range.
