  • Input current generator for buck-boost circuit control
    Patent number: 8525495
    Abstract: A control circuit for a buck-boost circuit includes an inductor current sensor and an input current generator. The input current generator accepts a signal from the inductor current sensor and outputs a synthesized and integrated signal representing the average input current to the buck-boost circuit. The input current generator averages the inductor current signal or a zero signal based on the state of the buck switch in the buck-boost circuit.

  • Controller for a buck-boost circuit
    Patent number: 8354827
    Abstract: A control circuit includes a controller that provides a master PWM signal indicative of a difference between a predetermined setpoint and a process signal. The control circuit also includes a PWM splitter circuit that receives the master PWM signal and provides a first PWM signal for a first switch and a second PWM signal for a second switch. The first PWM signal corresponds to a first portion of the master PWM signal and the second PWM signal corresponds to a second portion of the master PWM signal.
