Abstract
An electronic device includes a power stage, a switch and a controller. Power is transferred from an input through the power stage to an output. The switch turns on and off a current provided to the power stage for transferring the power. The controller turns on and off the switch. During a low-load mode, the controller causes the switch to operate with a constant on-time control.
