Description

Tracking dc/dc converters must track a reference voltage. However the rate of change in the reference voltage that the output voltage can successfully track is limited. This application report presents a typical application circuit and the reasons for these limitations along with the waveforms showing circuit performance when the reference voltage slew rates are increased above the maximum.
