Abstract: Disclosed is a constant power regulation type switch mode power supply. The constant power regulation type switch mode power supply includes a resonant converter for converting an input voltage according to a switching operation of a primary switch to output the converted input voltage to a secondary output end; a converter control unit for sensing the output voltage of the secondary output end to control a switching frequency of the primary switch; and a constant power control circuit for sensing the output voltage of the secondary output end to control a voltage gain of the resonant converter depending on the overloaded state. Thus, a load current of a secondary side is directly sensed and the gain is changed so that a load transfer from a primary side to the secondary side may be reduced.
