Abstract
A DC-DC converter has a high-side transistor series with a low-side transistor and an inductor connected to a node therebetween, a gate driver circuit has a high-side gate driver circuit coupled to the high-side transistor; a low-side gate driver circuit coupled to the low-side transistor; a minimum pulse with circuit coupled to one of the high-side and low-side gate, the minimum pulse width circuit adaptively controlling a pulse width of a drive signal to the high-side or low-side transistor by the propagation delay of the respective gate driver circuit.
