Abstract:
A printer includes a switching power supply circuit including a primary side circuit configured to perform a power switching operation, a secondary side circuit having a shunt regulator, a feedback configured to feed a comparison result between the output voltage output from the secondary side circuit and a reference voltage of the shunt regulator back to the primary side circuit to control the output voltage of the secondary side circuit, a control signal circuit configured to input a PSC signal input from an SOC to the photocoupler to control the output voltage of the secondary side circuit, and a switch circuit configured to cut off a current to be supplied to the shunt regulator in a case where the output voltage of the secondary side circuit is a low voltage in accordance with the input of the PSC signal.

Claim (Index 5):
A control method of a printing apparatus including switching power supply circuit including a primary side circuit configured to perform a power switching operation, a secondary side circuit having a shunt regulator and configured to output an output voltage to a load side, and a feedback circuit configured to feed a comparison result between the output voltage of the secondary side circuit and the reference voltage of the shunt regulator back to the primary side circuit to control the output voltage of the secondary side circuit, the method comprising:\n by switching power supply circuit, inputting a control signal to the feedback circuit to control the output voltage of the secondary side circuit, and cutting off a current to be supplied to the shunt regulator in a case where the output voltage of the secondary side circuit is decreased in accordance with the control signal.
