Abstract
Systems, methods, and apparatus for improving steady state operation of a pulse width modulator during transient and soft start events are described herein. An apparatus can include a phase component configured to adaptively modify a pulse width of a first pulse width modulated (PWM) output signal based on a pulse width of a PWM input signal. Further, the apparatus can include a power stage component configured to source at least one of a voltage or a current to a load based on the first PWM output signal. In one example, the phase component can be configured to linearly extend the pulse width of the first PWM output signal based on the pulse width of the PWM input signal. In another example, the phase component can be configured to adaptively modify the pulse width of the first PWM output signal based on a predetermined maximum pulse width.
