    Abstract: In addition to an output voltage control loop, a dead-time optimization loop is provided for a digital synchronous switching converter to dynamically adjust the dead-time for the power switches of the converter. It is extracted a minimal feedback signal at a steady state while the output voltage remains under a specification, and a maximal efficiency of the digital synchronous switching converter is thus obtained.

    Abstract: A hybrid control circuit and method combine analog circuit and digital circuit to generate digital PWM signals for a multiphase DC-DC converter to generate an output voltage. For current balance control, analog current error signals are generated by the analog circuit from analog phase current signals of the multiphase DC-DC converter and then converted into digital current error signals for calculating the duties of each phase of the multiphase DC-DC converter. Therefore, fewer bit devices can be used to achieve precise current balance control and the size and cost of the circuit can be reduced.
