  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 efficiency (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
  efficiency and reduces ripple voltage and currents in
  both the input and output capacitors, allowing the use
  of smaller п¬Ѓlter components.
