Abstract
The disclosure describes decreasing the overshoot and undershoots during the mode transitions of a Buck-Boost switching converter, without causing mode bounces. This is achieved by a main compensation capacitor of an error amplifier being charged or discharged, so that the output voltage level is shifted close to the target value. The expected behavior of the disclosure is contributed to two items, one is a mode transition detector, configured to detect mode transition among buck, buck-boost, boost, and ½f buck/boost modes, and the other is charge/discharge circuitry configured within one-clock cycle of a mode transition being detected.
