摘要： An apparatus includes first and second processors, a common memory, and a switch. The first processor executes an operating system, connects to a communication network and communicates with the communication network. The second processor operates independently of the operating system, connects to the communication network, and communicates with the communication network. The second processor writes, in the common memory, communication setting information being used by the second processor when the switch switches the connection destination from the second processor to the first processor. The first processor acquires the communication setting information, and sets the acquired communication setting information to the first processor. The switch switches the connection destination of the communication network from the second processor to the first processor after the communication setting information has been set to the first processor.

摘要： There are provided a control circuit of a DC-DC converter of a synchronous rectification system which can realize rapid lowering of an output voltage with low power consumption at the stop of power supply, and a control method thereof. While a power supply stop signal is at low level, a control part controls an NMOS transistor according to the output signals of a comparator and a flip-flop circuit. While the power supply stop signal is at high level, the control part masks a reverse current detection signal and the output signal of the flip-flop circuit to control the NMOS transistor according to a detection signal of a comparator. When a choke coil current is reversely flowed and an output voltage is lowered to an output reference voltage corresponding to a reference voltage, the NMOS transistor is brought to the non-conductive state to regenerate the electric power to an input terminal.

摘要： A DC-DC converter for decreasing power consumption and quickly increasing an output voltage. The converter includes a voltage generation circuit, a switching control circuit, a current detection circuit, and a step control circuit. An output transistor performs switching to generate the output voltage of the switching control circuit. The current detection circuit is connected to the voltage generation circuit to detect a load current, which is derived from the output voltage, and to generate a detection signal. A stop control circuit maintains the output transistor in an activated state in accordance with the detection signal and stops the operation of the switching control circuit when the load current is less than or equal to the load current.
