Abstract :
This paper proposes the hysteretic buck converter with thermister to minimize the output ripple votage. The conventional hysteretic buck converter shows fast response, but it suffers from the large ripple voltage due to the logic switching. The proposed hysteretic buck converter employs the switched-capacitor techniques with comparators to maintain the minimum ripple voltage. The simulation results demonstrate that the proposed circuit was able to reduce the output ripple voltage more than 20% with respect to the conventional ones.
