Abstract
The provided is an on-time generator circuit and a switching converter. The on-time generator circuit includes a ramp module configured to generate a ramp signal based on a drive signal of a main power transistor and an input voltage; a compensation module configured to generate a compensation signal based on the input voltage and a duty cycle; and a timing signal generation module configured to generate a timing signal based on the ramp signal, the compensation signal, and an output feedback signal. The compensation signal is used to offset delay time generated by the timing signal, making turn-on time (Ton) be preset Ton corresponding to the duty cycle, and keeping a switching frequency constant at different duty cycles.
