Abstract
A circuit includes an amplifier having a first input, a reference input, and an output. A pulse width modulator (PWM) controller has an input coupled to the output of the amplifier. A first switch has a control terminal coupled to an output of the PWM controller. A second switch has a second terminal coupled to the second terminal of the first switch, and has a control terminal coupled to the output of the PWM controller. An input of a current sensor is coupled to the second terminal of the first switch and is coupled to a second terminal of the second switch. An output of the current sensor is coupled to the first input of the amplifier. A duty cycle monitoring and reference signal adjustment circuit has an input coupled to the output of the PWM controller and has an output coupled to the reference input of the amplifier.
