APPARATUS AND METHODS FOR CONTROLLING A SWITCH MODE POWER CONVERTER USING A DUTY CYCLE STATE MACHINE

A power conversion system includes a switch mode power converter including a switch coupled to regulate an output voltage to a regulation value in response to a feedback signal. A controller is coupled to deliver a gate drive signal to the switch during an enabled control condition. The controller i...

More Information
Summary:A power conversion system includes a switch mode power converter including a switch coupled to regulate an output voltage to a regulation value in response to a feedback signal. A controller is coupled to deliver a gate drive signal to the switch during an enabled control condition. The controller is further coupled to inhibit the gate drive signal to the switch during an inhibited control condition. A duty cycle state machine included in controller is coupled to adjust a duty cycle of the gate drive signal according to a plurality of discrete duty cycle states.
