The filter circuit filters the hysteretic voltage to provide a filtered hysteretic voltage, such that a difference between the compensation voltage and the filtered hysteretic voltage is reduced in response to a load increase. The ramp circuit provides a repetitive ramp voltage which ramps between the filtered hysteretic voltage and the compensation voltage based on the pulse control signal. The current circuit increases a slope of the ramp voltage in response to the load increase. | 02-11-2010 |
