Abstract
A hysteresis generator provides a hysteresis parameter V_hyst to a hysteresis comparator of a voltage regulator. The hysteresis parameter V_hyst is a function of circuit components of the hysteresis generator, a voltage output Vout of the regulator, a voltage input Vin of the regulator, and a signal that drives one of a plurality of switches of the regulator. A switch driver drives the switches based on the hysteresis parameter. One or more of the circuit components of the hysteresis generator that provide the hysteresis parameter also define a hysteresis time period T_hyst. The hysteresis time period T_hyst defines in combination with a delay time period T_Td of the regulator, a switching time period T for the regulator that is substantially constant.
