摘要： In a self-diagnostic processing performed by a CPU, whether a vehicle is in an idle stop state is determined based on obtained vehicle operation information and engine operation information in order to perform abnormality detection processing. When an engine has stopped in a vehicle equipped with an idle stop function, electric power is supplied to electrical components of the vehicle, which means a battery supplies currents to the electrical components. Consequently, if a current measurement result obtained by measuring a current while the vehicle is stationary and an ignition is ON indicates that the measurement value is equal to or below a prescribed current value, the CPU determines that an abnormality has occurred in a measuring system.

摘要： In a DC/DC converter, when stepping up voltage from an input unit to an output unit or when stepping down voltage from the output unit to the input unit, a second driver IC outputs to a charge pump circuit a control signal for controlling a switching element so as to alternately repeat ON/OFF when a switching element is ON and a switching element is OFF. When stepping up voltage from the output unit to the input unit or when stepping down voltage from the input unit to the output unit, a first driver IC outputs to the charge pump circuit a control signal for controlling the switching element so as to alternately repeat ON/OFF when a switching element is ON and the switching element is OFF. As a result, the DC/DC converter can drive the charge pump circuit without providing an oscillation circuit.

摘要： A switching power supply includes: a switching type power supply circuit that converts an input voltage to generate an output voltage; and a control IC that executes feedback control that, based on a differential voltage between a target voltage and the output voltage from the power supply circuit, controls a switching element of the power supply circuit and causes the output voltage from the power supply circuit to converge to the target voltage. The control IC sets the target voltage for each predetermined period based on a value obtained by adding a preset value to the output voltage at a time of startup of the power supply circuit. Provided with this operation is a switching power supply that can precisely reduce an overshoot of the output voltage at the time of startup.
