Abstract:
When a ramp signal intersects a feedback related signal, a constant time switching regulator enters a first state and maintains in the first state for a constant time, and after the constant time ends, when the ramp signal exceeds the feedback related signal, the switching regulator enters a second state, while when the ramp signal does not exceed the feedback related signal, the switching regulator enters a third state. In the first state, the first end of an inductor is connected to input voltage and the second end of the inductor is connected to output voltage; in the second state, the first end is connected to ground and the second end is connected to output voltage; and in the third state, the first end is connected to input voltage and the second end is connected to ground.

Claim (Index 1):
A constant time buck-boost switching regulator, comprising:\n a power switch circuit, including an input switch unit and an output switch unit; the input switch unit being configured to operably switch a first end of an inductor between an input voltage and a ground, and the output switch unit being configured to operably switch a second end of the inductor between an output voltage and the ground; and a control circuit, when a ramp signal intersects a feedback related signal, the control circuit being configured to operably control the power switch circuit to enter a first state and maintain in the first state for a constant time, and after the constant time ends, when the ramp signal exceeds the feedback related signal, the control circuit being configured to operably control the power switch circuit to enter a second state, while when the ramp signal does not exceed the feedback related signal, the control circuit being configured to control the power switch circuit to enter a third state, wherein the feedback related signal is related to the output voltage; wherein, in the first state, the power switch circuit electrically connects the first end of the inductor to the input voltage and electrically connects the second end of the inductor to the output voltage; in the second state, the power switch circuit electrically connects the first end of the inductor to the ground and electrically connects the second end of the inductor to the output voltage; and in the third state, the power switch circuit electrically connects the first end of the inductor to the input voltage and electrically connects the second end of the inductor to the ground.
