How to Use a Multiphase Boost Converter
When the required system voltage exceeds the available supply voltage, a boost converter is typically an ideal solution. However, conventional standard boost topologies are not the only option. In certain application scenarios, phase-shifted multiphase boost converters can deliver superior performance: these converters achieve higher efficiency under heavy-load conditions while significantly reducing the required capacitance values for both the input and output stages.
