SLOPE COMPENSATOR AND DC-DC CONVERTER OF THE SAW TOOTH WAVE REDUCING THE GENERATION OF THE OFFSET VOLTAGE AND NON-LINEARITY

摘要

PURPOSE: By being created the saw tooth wave synchronized based on the current flowing in the switch in clock the slope compensator and DC-DC converter of the saw tooth wave simplify the design of circuit.;CONSTITUTION: A current sensing part(10) is created the sensing current by sensing the current of the outside element. The clock generator(30) is created the reference clock having the predetermined frequency. The saw tooth wave having the slope which the saw tooth generator(20) is compensated based on the sensing current is created. The saw tooth wave is synchronized in the reference clock, by recompensing the slope of the standards saw tooth wave which becomes based on the reference current with the sensing current the saw tooth generator is created the saw tooth wave.;COPYRIGHT KIPO 2010
