Abstract: A voltage converter circuit includes a high side transistor, a high side driver coupled to a control input of the high side transistor, a low side transistor coupled to the high side transistor at a switch node, and a current steering circuit coupled to the control input of the high side and to the switch node. During transition of the high side transistor to an on state, a current from the high side driver initially divides between the control input of the high side transistor and the current steering circuit, and as a voltage on the switch node increases, less of the current from the high side driver flows through the current steering circuit and more of the current from the high side driver flows to the control input of the high side transistor.

Abstract: A circuit and method for providing improved load transient response in a DC-DC converter. A DCM modulator is incorporated into the converter controller to generate a DCM enable signal for the driver circuits for the converter. During normal operation, the DCM enable signal will remain in a first state and the driver circuits will operate in a continuous conduction mode. However, upon a load transient, the DCM enable signal will change to a second state and the driver circuits will operate in a discontinuous conduction mode.
