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.
