  • POWER CONVERTER CONTROL
    Publication number: 20240039402
    Abstract: In some examples, a circuit includes a state machine. The state machine is configured to operate in a first state in which the state machine gates a pulse width modulation (PWM) signal provided for control of a power converter according to a first signal provided by a voltage control loop. The state machine is configured to operate in a second state in which the state machine gates the PWM signal according to a second signal provided by a current limit comparator. The state machine is configured to transition from the first state to the second state responsive to the second signal being asserted after the first signal is asserted in a switching cycle of the power converter. The state machine is configured to transition from the current state to the first state responsive to the first signal being asserted after the second signal in a switching cycle of the power converter.
