Multi-phase switching converter with over current protection and control method thereof |
摘要 |
A multi-phase switching converter includes a plurality of switching circuits and a controller. The output terminals of the plurality of switching circuits are coupled together to provide an output voltage to a load. The controller is configured to generate a plurality of control signals to control the plurality of switching circuits. When an over current condition of a current switching circuit of the plurality of switching circuits is detected, the controller skips the current switching circuit and successively turns on the remaining plurality of switching circuits that have not yet been turned on and where an over current condition has not been detected. |

1. A controller used in a multi-phase switching converter, wherein the multi-phase switching converter comprises a plurality of switching circuits with each of the switching circuits having an output terminal, and each of the output terminals are coupled together to provide an output voltage to a load, the controller is configured to generate a plurality of control signals to control the plurality of switching circuits, wherein
when an over current condition is detected in one of the plurality of switching circuits, the controller skips the current switching circuit with the detected over current condition and successively turns on the remaining plurality of switching circuits that have not yet been turned on and where an over current condition has not been detected. |
