Abstract
A driver circuit for use in a controller includes a signal generator coupled to generate a first control signal and a second control signal in response to a drive signal that is coupled to control switching of a secondary switch that is to be coupled to the driver circuit and referenced to a reference voltage that is greater than a ground reference voltage. A second switch is coupled to be controlled by the second control signal such that the reference voltage is substantially applied to a control of the secondary switch when the drive signal controls the secondary switch to be off. A first switch is coupled to be controlled by the first control signal such that the sum of the reference voltage and a first voltage is substantially applied to the control of the secondary switch when the drive signal controls the secondary switch on.
