Abstract:
A switching converter having a power stage with a main switch to convert an input voltage to an output voltage; a current sense circuit generating a current sense signal indicative of a current flowing through the main switch; a PWM generator generating a PWM signal; an OFF time controller generating an OFF time control signal relating to the input voltage and the output voltage; and a logic circuit generating a switching signal based on the OFF time control signal and the PWM signal to control the main switch.
