Abstract

PURPOSE: To reduce the conversion time to the step input, by fixing the switch circuit to ON or OFF depending on the output of the comparator every time the sampling pulse is fed.
CONSTITUTION: The filter circuit 12 having a small time constant is used, the vlotage switched with the switch circuit 11 driven with the pulse width signal is converted into analog feedback signal having greater ripple component, it is compared with the analog input signal at the comparator 3, and the pulse width signal is controlled so that the duty ratio of the output of the comparator 3 is 50%. Further, every time the sampling pulse SP is applied, the circuit 11 is fixed to ON or OFF depending on the output of the comparator 3. Thus, the conversion time can be reduced especially to a step input.
