Abstract
A phase activation control system for a multiphase DC/DC converter including an amplifier circuit and enable logic. The converter includes a first phase circuit providing a first PWM signal and has a reduce input for reducing duty cycle of the first PWM signal. The converter further includes a second phase circuit providing a second PWM signal and having an enable input and an increase input for increasing duty cycle of the second PWM signal. The amplifier circuit has an enable input, a current sense input for sensing output current of the converter and an output providing an adjust signal. The adjust signal is provided to the reduce input of the first phase circuit and to the increase input of the second phase circuit. The enable logic receives a phase enable signal and enables the amplifier circuit and the second phase circuit.
