Abstract
A dual mode controller is used to control switching circuitry by operating in either a voltage mode or a current mode on the basis of an output signal of the switching circuitry. The dual mode controller includes a voltage mode controller, a current mode controller, and a control circuit to control one of the voltage mode controller or current mode controller in response to the output signal of the switching circuit. The voltage mode controller and current mode controller can generate first and second pulse width modulated signals. The control circuit, in response to the output signal from the switching circuitry, operates the voltage mode controller and current mode controllers to provide one of the first pulse width modulated signal and the second pulse width modulated signal to an input of the switching circuitry.
