Abstract: A power converter includes a high side switch, a low side switch, a low side driver, a loading detector, a configurable regulator and a high side driver. The low side driver generates a low side drive signal to control the low side switch. The configurable regulator generates a regulation voltage, a magnitude of which is greater when the loading detector detects that the power converter has light loading than when the loading detector detects that the power converter has heavy loading. The high side driver generates a high side drive signal that switches between the input voltage and the regulation voltage to control the high side switch.
