Abstract
A main comparator compares a feedback voltage Vcorresponding to an output voltage Vof a DC/DC converter with a reference voltage Vand asserts a turn-on signal when the feedback voltage Vfalls below the reference voltage V. A timer circuit generates a turn-off signal Sthat transitions in level after an ON time Tproportional to (V−V/Vhas elapsed from assertion of the turn-on signal.
