  • DIRECTLY AMPLIFIED RIPPLE TRACKING CONTROL SCHEME FOR MULTIPHASE DC-DC CONVERTER
    Publication number: 20150091535
    Abstract: A controller for a multiphase power converter has a plurality of DC to DC converters coupled in parallel between a voltage source and a single output terminal is provided. The controller includes a voltage sensing circuit coupled to the output terminal. An internal pulse generating circuit is couplable to the voltage sensing circuit for generating an internal pseudo-pulse width modulated signal. An ON time signal distribution circuit is couplable to an output of the internal pulse generating circuit and couplable to driver circuit for driving each of the plurality of DC to DC converters. A multiphase power converter and method also disclosed.
