Abstract:

The present disclosure includes systems and methods using truncated ramp signal in switching regulators. In one embodiment, a switching regulator includes a truncated ramp generator to produce a truncated ramp signal comprising a ramp component and a constant component. A comparator receives the truncated ramp signal and a first signal, and in accordance therewith, produces a modulation signal. The first signal is based on an output voltage or an output current, and the first signal intersects the constant component of the truncated ramp signal in response to a change in the output voltage or output current, and in accordance therewith, the first switching transistor changes state.
