摘要： A direct current (DC)/DC converter capable of lowering power consumption and capable of being started in a short time is provided. A voltage generated at a second output capacitor is input to a power supply terminal. An input voltage is input to a high voltage terminal. A charging transistor is a N-channel Metal Oxide Semiconductor Field Effect Transistor disposed between the high voltage terminal and the power supply terminal and applied with a bias so that the charging transistor is normally on. In a first state, in which the voltage of the power supply terminal is lower than a specified first threshold voltage, a current limiting circuit limits a charging current flowing from the high voltage terminal to the power supply terminal, and in a second state in which the voltage is higher than a second threshold voltage, the current limiting circuit lowers the charging current substantially to zero.

摘要： The present invention provides an Alternating Current/Direct Current (AC/DC) converter employing measures not only against residual voltage but also to reduce power consumption. The AC/DC converter receives an Alternating Current (AC) voltage through a concentric plug and converts the AC voltage into a Direct Current (DC) voltage. A discharge path is disposed on a path from a discharge terminal to a ground terminal. A detection circuit compares a wave detection voltage with a predetermined threshold voltage, and enables the discharge path to be turned on when the wave detection voltage is continuously lower than the threshold voltage for a predetermined detection time.

摘要： A power supply adapter receives an AC voltage, converts the AC voltage into a DC voltage, and supplies the DC voltage to an electronic device. A DC/DC converter converts the voltage smoothed by a smoothing capacitor into the DC voltage. A device-side connector is connected to the DC/DC converter via a cable, and is configured to be detachably connected to the electronic device. The device-side connector includes a detection unit detecting whether or not the electronic device is connected, and generates a connection detection signal indicating whether or not the electronic device is connected. A control circuit of the DC/DC converter is connected to the detection unit of the device-side connector via the cable, and is set to an operating state when the connection detection signal indicates that the electronic device is connected, and is set to a non-operating state when the connection detection signal indicates that the electronic device is not connected.

摘要： A second control circuit is configured to switch a pulse signal to a level which turns off a second switching transistor when a coil current that flows through a primary winding reaches a predetermined threshold current. The second control circuit is configured to start a switching operation when a power supply for an electronic device is turned on, to set the threshold current to a first value when an intermediate voltage is higher than a predetermined level, and to set the threshold current to a second value that is lower than the first value when the intermediate voltage is lower than a predetermined level. A first control circuit is configured to start a switching operation upon receiving an instruction from a microcontroller to start operating.
