Abstract
A power supply with duty cycle limiting circuit includes a conversion circuit, a drive circuit, a control unit, and a duty cycle limiting circuit. The duty cycle limiting circuit converts a control signal into a control voltage, and determines whether a power switch of a power supply is turned off according to the control voltage and a threshold voltage to limit a duty cycle of the power switch.
