High power boost converters are becoming increasinglypopular among designers in the automotive, industrialand telecom industries. When power levels of 300W ormore are required, high effi ciency (low power loss) isimperative in the power train components to avoid theneed for bulky heat sinks and forced-air cooling. Interleavingpower stages (multiphase operation) improveseffi ciency and reduces ripple voltage and currents inboth the input and output capacitors, allowing the useof smaller fi lter components.
