Abstract
Systems and methods for transition control in a hybrid Switched-Mode Power Supply (SMPS). In some embodiments, a hybrid SMPS may include linear circuitry configured to produce an output voltage proportional to a variable duty cycle when the SMPS operates in linear mode and hysteretic circuitry coupled to the linear circuitry, the hysteretic circuitry configured to cause the duty cycle to assume one of two predetermined values when the SMPS operates in hysteretic mode. The hybrid SMPS may also include transition circuitry coupled to the linear circuitry and to the hysteretic circuitry, the transition circuitry configured to bypass at least a portion of the linear circuitry in response to the hybrid SMPS transitioning from the hysteretic mode to the linear mode.
