Dynamic Voltage Transition Control in Switched Mode Power Converters

A switched mode power converter, comprising:

• a power stage operable to output a voltage to a load;
• a main compensator operable to control switching of the power stage so that the voltage output by the power stage corresponds to a target voltage indicated to the switched mode power converter;
• and
• a voltage ramp circuit, comprising:
• a voltage ramp generator operable to generate a voltage ramp that starts at a first voltage corresponding to the target voltage and ends at a second voltage corresponding to a new target voltage;
• and
• a dynamic voltage transition compensation circuit responsive to the voltage ramp generator and operable to modify the output voltage response of the switched mode power converter based on one or more compensation parameters.

• a main compensator operable to control switching of the power stage so that the voltage output by the power stage corresponds to a target voltage indicated to the switched mode power converter;
• a ramp generator operable to control a slew rate of a dynamic voltage transition from the target voltage to a new target voltage;
• and
• an auxiliary compensator operable to override the main compensator and alter a dynamic voltage transition response of the main compensator.
