Abstract
A method of operating a switched-mode power supply (SMPS) includes starting up the switched-mode power supply by determining a rate of increase of a duty cycle of a pulse width modulated (PWM) signal based on an input voltage and a switching frequency of the SMPS; and generating the PWM signal having the duty cycle in accordance with the determined rate of increase.
