MOBILE PHONE AND DRIVING METHOD THEREOF

摘要

PURPOSE: A mobile phone and a driving method thereof are provided to minimize the damage on a device. CONSTITUTION: A memory(1200) stores a power lookup table necessary for the operation of plural elements according to the occurrence of an event. A converter(1320) applies the controlled power to the plural devices, and a PWM(Pulse Width Modulation) controller(1310) adjusts the pulse width of the power source to the converter. A DSP(Digital Signal Processor)(1110) controls the PWM controller according to the power lookup table corresponding to the occurring event. An error amplifier(EA) and a comparator(CP) reduces an error by comparing the input and output of the converter.
