Abstract
A switch control circuit and switch control method are provided. The switch control circuit and switch control method compensate an error of a load current that occurs because of the changing of a slope of an inductor current based on the increase and decrease of an input voltage. The switch control circuit includes a current compensation device that adjusts a gate on time based on a RC resistor and a control signal that senses a gate terminal of a control switch. The current compensation device compensates an error that occurs due to a signal delay to a gate terminal by increasing or decreasing a reference voltage or a sensing voltage, according to an increase or a decrease of an input voltage.
