4-Phase Boost Converter Delivers 384W with no Heat Sink
Design Note 453
Victor Khasiev
Introduction
High power boost converters are becoming increasingly
popular among designers in the automotive, industrial
and telecom industries. When power levels of 300W or
more are required, high efп¬Ѓciency (low power loss) is
imperative in the power train components to avoid the need for bulky heat sinks and forced-air cooling. Interleaving power stages (multiphase operation) improves
efп¬Ѓciency and reduces ripple voltage and currents in
both the input and output capacitors, allowing the use
of smaller п¬Ѓlter components.
