摘要： A semiconductor device for power supply control includes an over-current detection circuit which detects an over-current state on a secondary side of a transformer by comparing a voltage in proportion to current flowing in a primary-side winding wire with an over-current detection voltage; a control signal generation circuit which generates a control signal to turn off a switching element when the over-current detection circuit has detected the over-current state; and an over-current detection level generation circuit which generates the over-current detection voltage in accordance with an on-duty of a driving pulse of the switching element. The over-current detection level generation circuit is configured to generate the over-current detection voltage in accordance with: Vocp=Vint+a·ON Duty, where Vocp represents the over-current detection voltage, ON Duty represents the on-duty, Vint represents the over-current detection voltage to be a reference, and “a” represents a correction coefficient.

摘要： The lens drive device is provided with an autofocus drive unit and a shake correcting drive unit. A second support for supporting a shake correction moving part in a state separated from a shake correction fixed part has a power supply line for supplying power to an autofocus coil from the shake correction fixed part. An autofocus moving part has power supply line connection parts for electrically connecting the autofocus coil and the power supply line at two positions opposite each other in a first direction orthogonal to the optical axis. First supports for supporting the autofocus moving part in a state separated from an autofocus fixed part are disposed at two positions opposite each other in a second direction orthogonal to the optical axis of the autofocus moving part, and have a self-holding mechanism for holding the position of the autofocus moving part in the optical axis direction.
