Abstract
A controller for controlling a power stage having one or more phases is presented. The controller includes a reference circuit that generates a reference signal; a ramp generator generating a feedback ramp signal based on a feedback signal of the power stage; and a modulator generating a control signal for controlling at least one phase of the power stage. The control signal may include a series of pulses in which each pulse is associated with a corresponding phase of the power stage.
Claims20
A controller for controlling a power stage having one or more phases, the controller comprising
- a reference circuit adapted to generate a reference signal;
- a ramp generator adapted to generate a feedback ramp signal based on a feedback signal of the power stage;
- and
- a modulator adapted to generate a control signal for controlling at least one phase of the power stage.
A method of controlling a power stage having one or more phases, the method comprising:
- generating a reference signal;
- generating a feedback ramp signal based on a feedback signal of the power stage;
- and
- generating a control signal for controlling at least one phase of the power stage.
