Disclosed is an energy control circuit and method of a switching mode power supply (SMPS) for a plasma display panel (PDP), which includes an energy bank provided at an output of the SMPS for storing energy, and supplying current for driving the PDP; an active discharge controller for actively discharging the energy stored in the energy bank at time of power off for the PDP; a constant current unit and a constant voltage unit for recovering the actively discharged energy, and supplying a substantially constant current and a substantially constant voltage when the power off time occurs; a power converter for converting the energy actively discharged by the energy bank in response to the substantially constant voltage into power for the PDP following the power off time. |
