Abstract
An electronic device having multiple power output circuits that individually include a switch control input, a bypass control input, an output transistor and an output control circuit that includes an RC circuit with a resistor and a capacitor coupled to the output transistor gate and a bypass switch in parallel with the RC circuit resistor. The electronic device includes a controller that selects one of the power output circuits for a given power transfer cycle, closes the bypass switch to bypass the resistor of the selected power output circuit and turns the output transistor of the selected power output circuit on to transfer current from the inductor to a load of the selected power output circuit.
