摘要： A DC power supply capable of obviating undue resetting and malfunction of CPU, immediately after starting the operation of a switching regulator, by inputting sleep signals input asynchronously during a switching cycle of the switching regulator. In the DC power supply adapted to apply a DC voltage to an output terminal by selectively switching between a first voltage from a switching regulator and a second voltage, the switching regulator includes a first switching element and a inductor serially connected between an input terminal for receiving an input voltage and an output terminal, and a second switching element for use in synchronous rectification between the first switching element and the ground, together with a first drive circuit for driving the first switching element, a second drive circuit for driving the second switching element, and a control circuit for controlling the first and second drive circuits. The control circuit is configured to control signals to the first and second drive circuits such that the second switching element is kept turned off until the first switching element is turned on when the operation of the switching regulator is initiated.

摘要： A switching regulator converts an input voltage to a predetermined voltage and outputs the predetermined voltage to a load through an output terminal. The switching regulator includes a first switching element, a second switching element, a control switching circuit part, and a smoothing circuit. When a first operating mode in which a PFM control is performed and a voltage from the output terminal becomes a first voltage is shifted to a second operating mode in which a PWM control is performed and the voltage from the output terminal becomes a second voltage larger than the first voltage, the control switching circuit part increases the voltage from the output terminal stepwise progressively from the first voltage to the second voltage while performing the PWM control.

摘要： A digital TV broadcast signal receiver determines, as the best receiving direction, a receiving direction in which a digital TV broadcast signal can be accurately received. The digital TV broadcast signal receiver continuously scans all the receiving directions of a multi-directional antenna for each channel (S1), and demodulates received digital TV broadcast signals so as to detect BER values (S2), and also stores the detected BER values in a memory (S3). It further detects a minimum-error receiving direction or directions, among all the receiving directions, to give a minimum BER value, and determines whether or not there are multiple minimum-error receiving directions (S4). If there are multiple minimum-error receiving directions (YES in S4), it determines one of the minimum-error receiving directions as the best receiving direction for each channel with reference to BER values of receiving directions which are adjacent to the minimum-error receiving directions (S5 to S10).

摘要： A step-down switching regulator is disclosed that includes a first switching element, a smoothing circuit part including an inductor and a second switching element for synchronous rectification, a switching controller circuit part, and a reverse current detector circuit part that detects a reverse current flowing from the inductor to the second switching element and interrupts the reverse current by causing the switching controller circuit part to turn off the second switching element upon detection of the reverse current. Detecting a change in a set voltage, the reverse current detector circuit part stops, for a predetermined period of time, the operation of causing the switching controller circuit part to turn off the second switching element due to detection of the reverse current, and after the predetermined period of time is over, causes the switching controller circuit part to turn off the second switching element upon detection of the reverse current.

摘要： In a digital TV broadcast signal receiving system, an outdoor appliance comprises a tuner for receiving a TV broadcast signal transmitted from a TV tower or a broadcast satellite, a signal demodulator for demodulating the TV broadcast signal, and a first wireless interface for transmitting data with a second wireless interface provided in an indoor appliance. The indoor appliance further has a signal decoder for separating an audio signal and a visual signal and outputs them to a monitor apparatus. An appliance such as a personal computer having no tuner circuit can receive the TV broadcast signal if it has a wireless interface such as a wireless LAN. Furthermore, the data communication between the outdoor appliance and the indoor appliance is performed by wireless interfaces, so that a cable connecting between an outdoor appliance and an indoor appliance can be omitted.
