Abstract

A slope compensation circuit for use with current-programmed switching DC to DC converters is provided which allows operation of the switching converters in the 1-2 MHz range. The circuit avoids feedback of an output voltage which includes the effects of a partially discharged slope capacitor without adding unnecessary delay by using a switch to bypass the discharging slope capacitor and coupling an input stage of the slope compensation circuit to an output driver. A delay in feeding back the output of the slope compensation circuit is provided to assure that the bypassing switch has settled.
