How to Improve DC/DC Converter Performance with Phase Shifting Time Delay

Published by: Intersil

This article examines how to synchronize multiple DC/DC buck regulators in a Master/Slave configuration using phase shift time delay. Phase shifting multiple converters prevents ON time overlapping and reduces RMS current, ripple and input capacitor requirements, which will improve system EMI and power efficiency. This approach also eliminates the need for high input filtering and addresses the problems associated with beat frequencies.
