Abstract
A conventional single-ended, primary-inductance converter (SEPIC) has its switching frequency determined by a controller, which determines the duty cycle at which the switch operates by measuring differences between the SEPIC output voltage and a reference voltage. A controller is coupled to a switch of the SEPIC and provides a pulse train which determines the duty cycle and frequency at which the switch operates. The duty cycle is selectable between first and second percentages, the frequency is selectable between first and second frequencies, and the duty cycle and frequency are selected by the controller responsive to a voltage at an input voltage terminal of the SEPIC. Output voltage overshoot and undershoot are reduced.
