ABSTRACT:
A switching regulator includes a power stage, an output capacitor, a first reference voltage generator, a first virtual ripple generator, a comparator, and a constant-time trigger. The power stage includes a first switch, a second switch coupled to the first switch, and an output inductor coupled to the first switch and the second switch. The output capacitor coupled to the output inductor with an output voltage across the capacitor. The first virtual ripple generator is coupled to the first reference voltage generator for generating a first modulated reference voltage which reverses the output voltage according to the first reference voltage. The comparator includes a first input end coupled to the output inductor and the output capacitor and a second input end coupled to the first virtual ripple generator. The constant-time trigger is coupled between an output end of the comparator and a control end of the power stage.
