Single mode load tracking voltage mode controller with near minimum deviation transient response

A single-mode quasi constant frequency controller apparatus for controlling output voltage deviation during one or more load transients, the controller apparatus comprising:

• a polarity detector;
• a converter receiving one or more operational control parameters;
• a load tracking modulator configured to receive sensory inputs representative of a capacitor current polarity, and to control one or more power transistors of the converter such that an inductor current matches a load current cycle and reconstructs a desired inductor current ripple by splitting both an on-time for inductor charging and an off-time for inductor discharging into a current correction phase (CCP) and a ripple reconstruction phase (RRP), the load tracking modulator communicating the one or more operational control parameters for controlling the one or more power transistors, the load tracking modulator including a first half duty digital pulse width modulator and a second half duty digital pulse width modulator, the first half duty digital pulse width modulator and the second half duty digital pulse width modulator being configured to control the one or more power transistors based on an output of the polarity detector.
