Beschreibung
Zusammenfassung:	The invention discloses a heating table switching power supply device and a control circuit thereof, the switching power supply device comprises a flyback converter and two output ends of a switching power supply, one output end is connected with a heating table lifting motor for working of the heating table lifting motor, and the other output end is connected with a heating table power system except the heating table lifting motor for working of the heating table lifting motor. The heating table electric system works; different working voltages are respectively output through two output ends of the flyback converter; and the power is respectively used for the heating table lifting motor and the heating table power system. The switching power supply respectively outputs two paths of power supply voltages DC24V and DC5V, one path of DC24V independently supplies power for the motor to work, the other path of DC5V supplies power for the system to work (a DC-DC step-down IC does not need to be additionally added)
