Abstract: Slew rate in a power supply gets limited by the inductance value and the voltage across the inductor. Slew rate can be increased by reducing the inductance, but it results in higher inductor current ripple and hence higher losses in the power converters. In this paper, we present a novel scheme for increasing the slew rate without reducing the inductance value. The scheme operates only when there is a demand in the slew rate and restores to the normal operating conditions during steady state operation. It provides reduced voltage undershoots and faster settling times in output voltage during load transients. The proposed scheme is tested on a 1V/12.5 A buck converter switching at 1MHz and the experimental results are presented. ©2008 IEEE.
