Applying a motor-controller IC for buck-boost conversion

Posted: 28 Sep 2007     Print Version  Bookmark and Share

Keywords:buck-boost converters  motor-controller IC  MOSFET 

Several power supply topologies, including SEPIC and flyback converters, generate a non-isolated, positive DC voltage from a positive DC input voltage range that extends both above and below the output. But there are alternatives. Buck-boost converters like the TPS63000 regulate the output by switching an inductor with four FETs in a full-bridge configuration. While these highly integrated devices were designed with this application in mind, PWM motor controller ICs can drive the output FETs in a full-bridge configuration in both the buck and boost modes with a seamless transition between the two modes. They're a viable option in applications where high levels of integration sometimes limit flexibility.
