Under the Hood of a DC/DC Boost Converter
www.ti.comUnlike a buck-derived topology, energy flows to the load during the OFF time of the control switch. The effect of any control action during the ON time of the switch is delayed until the switch is turned OFF. For example, during a load-step increase, the output voltage drops due to insufficient stored energy in the inductor. The
