  • Cascaded buck boost DC to DC converter and controller for smooth transition between buck mode and boost mode
    Patent number: 9525350
    Abstract: Cascaded buck boost DC to DC conversion systems, controllers and methods are presented, in which a buck converter stage is pulse width modulated in a first mode and a boost converter stage is pulse width modulated in a second mode, with the pulse width modulation using a first one of peak current control in valley current control in the first mode, and using the other of peak current control in valley current control in the second mode, and operation is switched between the first and second modes based on an on-time of a low side driver switch of the buck converter stage or the boost converter stage.
