description The utility model discloses a dynamic adjustment circuit, system and switching power supply, this dynamic adjustment circuit still include the preset module of load feedback voltage initial value for when switching power supply's output voltage is less than the default, export a load feedback voltage initial value, the constant voltage control module for reference voltage according to load feedback voltage initial value and the preset module output of reference voltage calculates the interrupted time that is used for the control impuls of control power switch conduction and shutoff, and then control switch power supply's output voltage, and wherein, the power switch is used for control switch power supply's energy transfer. The utility model discloses a put an initial value for load feedback voltage, improved the DC operating point of this charger to make the control impuls's of constant voltage control module output the interrupted time reduce or even for zero, make the output voltage of charger to promote f
