Abstract
Concerning a low-voltage and high-current output DC-DC converter such as a voltage regulator module used for a 64-bit microprocessor, synchronization with paralleled current-doubler rectifiers has been considered for improvement in dynamic response. As a result, the output voltage deviation of 50 mV at a slew rate of 300 A//spl mu/s has been performed on a prototype with an output of 1.3 V/130 A.
