%X A digital control DC-DC converter is presented,which uses a single comparator.It adopts variable step feedback algorithm and duty cycle dither,and obtains 7 bits voltage resolution with PWM signal of only 6 bit binary duty cycle.Because of the variable step feedback algorithm,this converter has better dynamic performance than those with constant step,and has low complexity.This converter works at a switching frequency of 1MHz,and the controller's power consume is less than 0 5mW.It is suitable to be integrated with other digital systems for its small portion of analog circuit.
