CAMERA MODULE REDUCED SWITCHING NOISE

摘要

PURPOSE: A camera module in which switching noise is reduced is provided to eliminate a high frequency switching noise element by eliminating the peak of a high frequency element. CONSTITUTION: A VCM(Voice Coil Module) of a camera module includes an actuator and a driver IC(Integrated Circuit)(100). When on or off switching is generated in a switching unit(120) of the driver IC, a high frequency noise element is generated in a waveform. A high-frequency elimination unit(110) of the driver IC eliminates the high frequency noise element. An energy storage unit(130) of the driver IC outputs or stores energy through a signal applied to the switching unit.
