  • SWITCHING POWER CONVERTER CIRCUIT AND CONVERSION CONTROL CIRCUIT AND METHOD THEREOF
    Publication number: 20240097567
    Abstract: A conversion control circuit is configured to generate a PWM (pulse width modulation) signal to control a power switch for switching an inductor to convert an input voltage to an output voltage. The steps of generating the PWM signal includes: enabling the PWM signal at a rising edge of a clock signal to turn on the power switch; disabling the PWM signal to turn off the power switch when an on-time exceeds a predetermined minimum on-time and the output voltage has reached an output level; triggering a next rising edge of the clock signal when the off-time exceeds a predetermined minimum off-time, the output voltage has not reached the output level, and a present cycle period of the clock signal has reached a predetermined cycle period.
