Abstract
Circuits arranged to produce first and second outputs produced by first and second switch-mode converters, respectively, wherein each switch-mode converter comprises a converter input, a converter output, a converter controller, a converter controller enable input arranged to provide power to the controller, and a semiconductor power switching device coupled between the converter input and the converter controller. A first output of the first converter and a second output of the second converter are each arranged to produce a voltage of higher magnitude than the voltage at the respective converter controller enable input and converter input when the converter controller is enabled. Methods of controlling first and second outputs from first and second switch-mode converters are also disclosed.
