Abstract:
A power supply apparatus is provided, that supplies a bus voltage V BUS  to a detachable device. A DC/DC converter generates a DC voltage V OUT  used as the bus voltage V BUS . A USB controller receives the DC voltage V OUT  as a power supply voltage, and detects whether or not the device is connected. The DC/DC converter generates the DC voltage V OUT  such that (i) when the device is detected, the DC voltage V OUT  has a specified voltage level, and such that (ii) when the device is not detected, the DC voltage V OUT  has a voltage level that is lower than the specified voltage level and that is higher than a minimum operating voltage level required to operate the USB controller.

Claim (Index 16):
The power supply apparatus according to  claim 12 , wherein the DC/DC converter is configured as an insulated DC/DC converter,\n and wherein the DC/DC converter comprises:\n a transformer having a primary winding and a secondary winding; \n a secondary-side rectifier circuit that is connected to the secondary winding, so as to output the DC voltage; \n a switching transistor connected to the primary winding; \n a photocoupler comprising a light-emitting element and a light-receiving element; \n a feedback circuit comprising a shunt regulator that is connected to the light-emitting element of the photocoupler, and that drives the light-emitting element with a current that corresponds to a difference between a detection voltage that corresponds to the DC voltage and a reference voltage; and \n a primary-side controller that switches on and off the switching transistor according to a feedback signal that corresponds to a current that flows through the light-receiving element of the photocoupler.
